144-512: During the period of the four Southern Dynasties (Nan Chao) from 420 to 589 A.D. when China's national capital was in Jiankang (modern Nanjing ), Danyang was the hometown of the emperors of the Southern Qi (479-502) and Liang Dynasties (502-557), who were buried in the countryside outside the city. Today 11 of these Southern Dynasties imperial tombs can still be found to the east and northeast of

288-591: A dot map showing corn production in Indiana or a shaded area map of Ohio counties , divided into numerical choropleth classes. As the volume of geographic data has exploded over the last century, thematic cartography has become increasingly useful and necessary to interpret spatial, cultural and social data. A third type of map is known as an "orienteering," or special purpose map. This type of map falls somewhere between thematic and general maps. They combine general map elements with thematic attributes in order to design

432-532: A star map on the equidistant cylindrical projection. Although this method of charting seems to have existed in China even before this publication and scientist, the greatest significance of the star maps by Su Song is that they represent the oldest existent star maps in printed form. Early forms of cartography of India included depictions of the pole star and surrounding constellations. These charts may have been used for navigation. Mappae mundi ('maps of

576-530: A 'sense of the other' in relation to nonconforming maps." Depictions of Africa are a common target of deconstructionism . According to deconstructionist models, cartography was used for strategic purposes associated with imperialism and as instruments and representations of power during the conquest of Africa. The depiction of Africa and the low latitudes in general on the Mercator projection has been interpreted as imperialistic and as symbolic of subjugation due to

720-455: A brief interlude from 552 to 555), they are sometimes grouped together with Eastern Wu and Eastern Jin under the historiographic term "the Six Dynasties ". The rulers of these short-lived dynasties were generals who seized and then held power for several decades but were unable to securely pass power of rule onto their heirs to continue their dynasty successfully. Emperor Wu of Liang (502–549)

864-445: A ceasefire and peace. However, Hou thought that peace was unsustainable, so he broke the ceasefire and captured the palace, leading to the slaughter of the nearby populace. Emperor Wu was starved to death and after the short puppet reigns of crown prince Xiao Gang and Xiao Dong, Hou seized power and established the Han dynasty. In spite of conquering Jiankang, Hou essentially only controlled

1008-428: A decreased focus on production skill, and an increased focus on quality design , the attempt to craft maps that are both aesthetically pleasing and practically useful for their intended purposes. A map has a purpose and an audience. Its purpose may be as broad as teaching the major physical and political features of the entire world, or as narrow as convincing a neighbor to move a fence. The audience may be as broad as

1152-399: A different direction. To print from the finished plate, ink is spread over the metal surface and scraped off such that it remains only in the etched channels. Then the plate is pressed forcibly against the paper so that the ink in the channels is transferred to the paper. The pressing is so forceful that it leaves a "plate mark" around the border of the map at the edge of the plate, within which

1296-504: A diplomatic faux pas, he incited the anger of Yuwen Tai, the leading general of Western Wei, which resulted in him being deposed and dying. Western Wei set up the puppet state of Western Liang with capital at Jiangling. Northern Qi also had designs on the Liang throne and sent an expedition under the banner of a cousin of Emperor Yuan. Chen Baxian and Wang Sengbian set up the last surviving son of Emperor Yuan, Xiao Fangzhi , as Liang ruler, but he

1440-468: A fall in their social status, causing widespread desertion of troops. Faced with shortage of troops, Eastern Jin generals were often sent on campaigns to capture non-Han indigenous peoples in the south to draft them into the military. The Eastern Jin dynasty fell not because of external invasion, however, but because Liu Yu (Emperor Wu of Liu Song) seized the throne from the Emperor Gong of Jin and founded

1584-482: A few metres; the invention of OpenStreetMap in 2004, a global digital counter-map that allowed anyone to contribute and use new spatial data without complex licensing agreements; and the launch of Google Earth in 2005 as a development of the virtual globe EarthViewer 3D (2004), which revolutionised accessibility of accurate world maps, as well as access to satellite and aerial imagery. These advances brought more accuracy to geographical and location-based data and widened

1728-682: A formidable general to the great delight of the Northern Wei. Thus, they were unable to capitalize when Northern Wei suffered the Wuqi Incident . Starting in 445, Northern Wei, taking advantage of Liu Song's weakness, made major incursions in the lands between the Yangtze and the Huai (modern Shandong, Hebei, and Henan) and devastating six provinces. Emperor Wen lamented that if Tan were still alive, he would have prevented Northern Wei advances. From then on, Liu Song

1872-408: A general-purpose world map because regions are shown as increasingly larger than they actually are the further from the equator they are. Mercator is also credited as the first to use the word "atlas" to describe a collection of maps. In the later years of his life, Mercator resolved to create his Atlas, a book filled with many maps of different regions of the world, as well as a chronological history of

2016-524: A half to get to Shanghai and about 30 minutes to get to Nanjing , the provincial capital. Direct service to Beijing from Danyang North Station takes about 4 hours and 30 minutes. Danyang is known for its barley gruel and huangjiu (yellow wine), which has traditional medicinal properties. Kaitai Bridge is a historic stone arch bridge in the city. Southern and Northern Dynasties#The Southern dynasties The Northern and Southern dynasties ( Chinese : 南北朝 ; pinyin : Nán běi cháo )

2160-576: A map is what comprise a map's deconstruction . A central tenet of deconstructionism is that maps have power. Other assertions are that maps are inherently biased and that we search for metaphor and rhetoric in maps. It is claimed that the Europeans promoted an " epistemological " understanding of the map as early as the 17th century. An example of this understanding is that "[European reproduction of terrain on maps] reality can be expressed in mathematical terms; that systematic observation and measurement offer

2304-441: A map with a specific audience in mind. Oftentimes, the type of audience an orienteering map is made for is in a particular industry or occupation. An example of this kind of map would be a municipal utility map. A topographic map is primarily concerned with the topographic description of a place, including (especially in the 20th and 21st centuries) the use of contour lines showing elevation. Terrain or relief can be shown in

2448-575: A metaphor for power. Political leaders could lay claim to territories through the use of maps, and this was greatly aided by the religious and colonial expansion of Europe. The Holy Land and other religious places were the most commonly mapped during the Renaissance. In the late 1400s to the late 1500s, Rome, Florence, and Venice dominated map-making and trade. It started in Florence in the mid-to late 1400s. Map trade quickly shifted to Rome and Venice but then

2592-419: A mistake when a former garrison officer organized another rebellion in the years 526–527. The underlying cause of these wars was the growing rift between the governing aristocracy which was increasingly adopting Han-style sedentary policies and lifestyles and their nomadic tribal armies who continued to preserve the old steppe way of life. The Northern Wei court was betrayed by one of their own generals, who had

2736-526: A monk, but each time he was persuaded to return by extravagant court donations to Buddhism. Furthermore, since Buddhists and Daoists were exempt from taxation, nearly half of the population fraudulently named themselves as such, badly damaging state finances. Imperial clansmen and officials were also greedy and wasteful. Emperor Wu was willing to accept generals who defected from Northern Wei. So when Northern Wei suffered major revolts in their northern garrison towns , he sent his general Chen Qingzhi to support

2880-659: A new conception referring to the two as distinct 'Northern' and Southern' parallels, using unique local customs to distinguish themselves and compete for legitimacy. It was during the Northern and Southern dynasties period that the earliest recorded mass migration of ethnic Han to southern China (south of the Yangtze River ) took place. This sinicisation helped to develop the region from its previous state of being inhabited by isolated communities separated by vast uncolonized wilderness and other non-Han ethnic groups. During this period,

3024-402: A peace offering. Despite Emperor Wu's assurances, Hou decided to rebel in the name of Xiao Dong , the grandson of the former crown prince Xiao Tong who died in 531 and was removed from crown prince because of conflicts with his father. Hou surprised Emperor Liang by besieging the Liang capital at Jiankang. Attempts by Liang forces to break the siege failed, and Emperor Wu was forced to negotiate

3168-461: A policy of strict social distinction between them and their Han subjects. Ethnic Han were drafted into the bureaucracy, employed as officials to collect taxes, etc. However, the Han were kept out of many higher positions of power. They also represented the minority of the populace where centers of power were located. Widespread social and cultural transformation in northern China came with Emperor Xiaowen of Northern Wei (reigned 471–499), whose father

3312-460: A rare move, Ortelius credited mapmakers who contributed to the atlas, the list of which grew to 183 individuals by 1603. In the Renaissance , maps were used to impress viewers and establish the owner's reputation as sophisticated, educated, and worldly. Because of this, towards the end of the Renaissance, maps were displayed with equal importance of painting, sculptures, and other pieces of art. In

3456-518: A relatively stable formation. After a 249 coup by Sima Yi , the Sima family essentially controlled Cao Wei and the conquest of Shu Han by Cao Wei rapidly followed. Following a failed coup by the ruling Cao family against the Sima family, the final Cao ruler abdicated. Sima Yan (Emperor Wu of Jin) then founded the Western Jin dynasty and the conquest of Eastern Wu by Western Jin occurred in 280, ending

3600-531: A standard as compared to the 1:50,000 scale Canadian maps. The government of the UK produces the classic 1:50,000 (replacing the older 1 inch to 1 mile) " Ordnance Survey " maps of the entire UK and with a range of correlated larger- and smaller-scale maps of great detail. Many private mapping companies have also produced thematic map series. Thematic cartography involves maps of specific geographic themes, oriented toward specific audiences. A couple of examples might be

3744-416: A thin sheet of wax over the metal plate and uses ink to draw the details. Then, the engraver traces the lines with a stylus to etch them into the plate beneath. The engraver can also use styli to prick holes along the drawn lines, trace along them with colored chalk, and then engrave the map. Lines going in the same direction are carved at the same time, and then the plate is turned to carve lines going in

3888-400: A variety of ways (see Cartographic relief depiction ). In the present era, one of the most widespread and advanced methods used to form topographic maps is to use computer software to generate digital elevation models which show shaded relief. Before such software existed, cartographers had to draw shaded relief by hand. One cartographer who is respected as a master of hand-drawn shaded relief

4032-450: Is a close reproduction of a 1698 work by Nicolas de Fer . De Fer, in turn, had copied images that were first printed in books by Louis Hennepin , published in 1697, and François Du Creux, in 1664. By the late 18th century, mapmakers often credited the original publisher with something along the lines of, "After [the original cartographer]" in the map's title or cartouche . In cartography, technology has continually changed in order to meet

4176-467: Is an iconic example. Although the most widely used map of "The Tube," it preserves little of reality: it varies scale constantly and abruptly, it straightens curved tracks, and it contorts directions. The only topography on it is the River Thames , letting the reader know whether a station is north or south of the river. That and the topology of station order and interchanges between train lines are all that

4320-456: Is left of the geographic space. Yet those are all a typical passenger wishes to know, so the map fulfills its purpose. Modern technology, including advances in printing , the advent of geographic information systems and graphics software , and the Internet , has vastly simplified the process of map creation and increased the palette of design options available to cartographers. This has led to

4464-564: Is one of the largest eyeglass merchandise centers in China. Built in 1986, the market center's construction occurred in three phases. It subsequently merged with the Huayang Spectacles and Yunyang Spectacles markets. It covers an area of over 344,445 square feet (32,000 square meters). There are three railway stations in Danyang: The high-speed trains (typically, listed in schedules as G-series or D-series trains) take about an hour and

4608-465: Is the Swiss professor Eduard Imhof whose efforts in hill shading were so influential that his method became used around the world despite it being so labor-intensive. A topological map is a very general type of map, the kind one might sketch on a napkin. It often disregards scale and detail in the interest of clarity of communicating specific route or relational information. Beck's London Underground map

4752-460: Is the earliest known map is a matter of some debate, both because the term "map" is not well-defined and because some artifacts that might be maps might actually be something else. A wall painting that might depict the ancient Anatolian city of Çatalhöyük (previously known as Catal Huyuk or Çatal Hüyük) has been dated to the late 7th millennium BCE. Among the prehistoric alpine rock carvings of Mount Bego (France) and Valcamonica (Italy), dated to

4896-481: Is the study and practice of making and using maps . Combining science , aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: Modern cartography constitutes many theoretical and practical foundations of geographic information systems (GIS) and geographic information science (GISc). What

5040-548: The Berlin Conference of 1884–1885. Before 1749, maps of the African continent had African kingdoms drawn with assumed or contrived boundaries, with unknown or unexplored areas having drawings of animals, imaginary physical geographic features, and descriptive texts. In 1748, Jean B. B. d'Anville created the first map of the African continent that had blank spaces to represent the unknown territory. In understanding basic maps,

5184-543: The Far East (which he learned through contemporary accounts from Arab merchants and explorers) with the information he inherited from the classical geographers, he was able to write detailed descriptions of a multitude of countries. Along with the substantial text he had written, he created a world map influenced mostly by the Ptolemaic conception of the world, but with significant influence from multiple Arab geographers. It remained

5328-606: The Former Qin , the defeat of the Former Qin at the Battle of Fei River resulted in the collapse of the Former Qin. The grandson of the last prince of Dai Tuoba Shiyiqian , Tuoba Gui restored the fortunes of the Tuoba clan, renaming his state Wei (now known as Northern Wei) with its capital at Shengle (near modern Hohhot ). Under the rule of Emperors Daowu (Tuoba Gui), Mingyuan , and Taiwu ,

5472-512: The Kassite period (14th – 12th centuries BCE). The oldest surviving world maps are from 9th century BCE Babylonia . One shows Babylon on the Euphrates , surrounded by Assyria , Urartu and several cities, all, in turn, surrounded by a "bitter river" ( Oceanus ). Another depicts Babylon as being north of the center of the world. The ancient Greeks and Romans created maps from

5616-705: The Liu Song dynasty , which officially began the Northern and Southern dynasties period. The Northern dynasties began in 439 when the Northern Wei conquered the Northern Liang to unite northern China and ended in 589 when the Sui dynasty extinguished the Chen dynasty . It can be divided into three time periods: Northern Wei ; Eastern and Western Weis ; Northern Qi and Northern Zhou . The Northern, Eastern, and Western Wei along with

5760-737: The North Star at night or the Sun at noon. Advances in photochemical technology, such as the lithographic and photochemical processes , make possible maps with fine details, which do not distort in shape and which resist moisture and wear. This also eliminated the need for engraving, which further speeded up map production. In the 20th century, aerial photography , satellite imagery , and remote sensing provided efficient, precise methods for mapping physical features, such as coastlines, roads, buildings, watersheds, and topography. The United States Geological Survey has devised multiple new map projections, notably

5904-504: The Northern Zhou dynasty (557–580). The Northern Qi inherited the primary recruiting grounds of the Northern Wei army; previously, five out of six Northern Wei military officers came from the eastern territories, particularly the local armed forts of Han military families and steppe tribes who had settled in these areas. The members of these military families, both men and women, were often expert riders and archers. Like its predecessor

As the Wei Shu and Song Shu testify, there was a shift from imperial rhetoric denouncing the other side as illegitimate barbarians, towards

6336-503: The Three Disasters of Wu . At this late stage in his life, Emperor Taiwu meted out cruel punishments, which led to his death in 452 at the hands of the eunuch Zong Ai . His death sparked off turmoil that only ended with the ascension of Emperor Wencheng later that same year. Wang Yu  [ zh ] , an ethnic Qiang court eunuch and the favourite of Empress Dowager Wenming, patronized Buddhism lavishly. He constructed Cave 9–10,

6480-569: The Werner projection . This was an equal-area, heart-shaped world map projection (generally called a cordiform projection) that was used in the 16th and 17th centuries. Over time, other iterations of this map type arose; most notable are the sinusoidal projection and the Bonne projection . The Werner projection places its standard parallel at the North Pole; a sinusoidal projection places its standard parallel at

6624-477: The printing press , quadrant , and vernier allowed the mass production of maps and the creation of accurate reproductions from more accurate data. Hartmann Schedel was one of the first cartographers to use the printing press to make maps more widely available. Optical technology, such as the telescope , sextant , and other devices that use telescopes, allowed accurate land surveys and allowed mapmakers and navigators to find their latitude by measuring angles to

6768-472: The 17th century, European cartographers both copied earlier maps (some of which had been passed down for centuries) and drew their own based on explorers' observations and new surveying techniques. The invention of the magnetic compass , telescope and sextant enabled increasing accuracy. In 1492, Martin Behaim , a German cartographer and advisor to the king John II of Portugal , made the oldest extant globe of

6912-517: The 4th millennium BCE, geometric patterns consisting of dotted rectangles and lines are widely interpreted in archaeological literature as depicting cultivated plots. Other known maps of the ancient world include the Minoan "House of the Admiral" wall painting from c.  1600 BCE , showing a seaside community in an oblique perspective, and an engraved map of the holy Babylonian city of Nippur , from

This treaty's significance draws from the interaction between the two sides, and the intermediaries who were drawn from a wide variety of nationalities. Maps of the Enlightenment period practically universally used copper plate intaglio, having abandoned the fragile, coarse woodcut technology. Use of map projections evolved, with

7200-542: The Chen dynasty. Chen Shubao relied on the natural barrier of the Yangtze River and continued as always with his festive and licentious activities. The next year, Sui forces captured the Chen capital of Jiankang. Chen Shubao and his favorite concubine Zhang Lihua attempted to hide in a well but eventually were captured by Sui forces, thus ending the Chen dynasty. After the failure of the Liu Song's efforts to form an alliance with

7488-522: The Eastern Jin attempted to draft the dependents of the great families, the court was quickly overthrown. However, with the fall of the Eastern Jin in 420, the balance of power shifted in favour the central government. The subsequent Liu Song, Qi, Liang and Chen dynasties were ruled by military leaders from lowly social backgrounds. They gradually stripped the powerful clans of military power, authority and wealth. The emperors stationed regional armies around

7632-418: The Eastern Jin court. In order to gain popularity to take the throne he led expeditions against the Sixteen Kingdoms, capturing Shandong , Henan and, briefly, Guanzhong by 416. He gave up Guanzhong to try to take the throne. Because he believed in a prophecy saying there would be one more emperor after Emperor An , he deposed the former and, soon afterwards, his replacement, Emperor Gong in 420, ending

7776-435: The Eastern Jin dynasty. Even after crowning himself Emperor Wu, Liu Yu remained frugal. However, he did not care for education and trusted unsavory people. He felt that the nobility had too much power, so he tended to appoint the lower classes to government positions and gave military power to imperial kinsmen. Ironically, because the imperial kinsmen stabilized their military power and wished to gain political power, Emperor Wu

Emperor Xiaowen also moved the capital city from Pingcheng to one of China's old imperial sites, Luoyang , which had been the capital during the earlier Eastern Han and Western Jin dynasties. The new capital at Luoyang was revived and transformed, with roughly 150,000 Xianbei and other northern warriors moved from north to south by

8064-453: The Huai River. Northern Zhou instead took advantage of Northern Qi's weakness and following their defeat of Northern Qi, in 577, they sent troops to the territories south of the Huai River, where they decisively defeated the Chen dynasty forces. The Chen dynasty was in imminent danger. In a stroke of fortune, Northern Zhou's Emperor Wu suddenly died and his general Yang Jian attempted to take

8208-627: The Later Yan capital of Pingcheng (modern-day Datong). That same year he declared himself Emperor Daowu. Due to Emperor Daowu's cruelty, he was killed by his son Tuoba Shao, but crown prince Tuoba Si managed to defeat Tuoba Shao and took the throne as Emperor Mingyuan. Though he managed to conquer Liu Song 's province of Henan, he died soon afterward. Emperor Mingyuan's son Tuoba Tao took the throne as Emperor Taiwu. Due to Emperor Taiwu's energetic efforts, Northern Wei's strength greatly increased, allowing them to repeatedly attack Liu Song. After dealing with

Liu Song founder Liu Yu was originally a leader of the Army of the Northern Garrison ( Chinese : 北府軍 ) that notably won the Battle of Fei River in 383. In 404, he helped suppress Huan Xuan 's rebellion, leading to his dominance over

8496-604: The Northern Wei court launched the sinicization movement. Northern gentry were therefore highly militarized as compared to their refined southern counterparts, and this distinction persisted well into the Sui and Tang dynasties centuries later. In the Sixteen Kingdoms period, the Tuoba family of the Xianbei were the rulers of the state of Dai (Sixteen Kingdoms) . Although it was conquered by

8640-479: The Northern Wei military forces dominated the Liu Song forces, they took heavy casualties. The Northern Wei forces plundered numerous households before returning north. At this point, followers of the Buddhist Gai Wu ( 蓋吳 ) rebelled. After pacifying this rebellion, Emperor Taiwu, under the advice of his Daoist prime minister Cui Hao , proscribed Buddhism — the first of the persecutions of Chinese Buddhism known as

He killed them in turn and crowned himself as Emperor Ming of Southern Qi . Using

9072-661: The Northern Zhou were established by the Xianbei people while the Northern Qi was established by a Xianbei-influenced ethnic Han. In the north, local ethnic Han gentry clans responded to the chaos by constructing fortified villages. Clans would then carve de facto fiefs out of these highly cohesive family-based self-defense communities. Lesser peasant families would work for the dominant clan as tenants or serfs. The chaos also led these Han gentry families to avoid government service, before

10800-464: The country selling their services to the warring princes and plundering the populace. These upheavals devastated the south which eased the fall of the south to the Sui dynasty. Under the later waning leadership of the Chen dynasty, the southern Chinese were unable to resist the military power amassed in the north by Yang Jian, who declared himself Emperor Wen of Sui and invaded the south. Aboriginal chiefs played an important active role in adapting to

10944-523: The country under the command of their imperial relatives, recruited officers from humble backgrounds and appointed low-ranking officials to monitor the powerful elites occupying the top government posts. The southern aristocracy declined with the rise of the Indian Ocean trade in the mid 5th century, which led to the court revenues shifting to trade and the disappearance of the caste by the Chen dynasty. As landowning aristocrats were unable to convert cash from

11088-496: The culmination of many map-making techniques incorporated into Chinese mercantile cartography. In 1689, representatives of the Russian tsar and Qing Dynasty met near the border town of Nerchinsk, which was near the disputed border of the two powers, in eastern Siberia. The two parties, with the Qing negotiation party bringing Jesuits as intermediaries, managed to work a treaty which placed

11232-424: The death of Emperor Wen, his son, the weak-willed Chen Bozong, took power and became Emperor Fei of Chen . His uncle, Chen Xu, after essentially controlling the country through his short reign, eventually deposed him and took power as Emperor Xuan of Chen . At that time, the Northern Zhou intended to conquer Northern Qi and thus invited the Chen dynasty to help. Emperor Xuan agreed to help because he wanted to recover

11376-433: The demands of new generations of mapmakers and map users. The first maps were produced manually, with brushes and parchment; so they varied in quality and were limited in distribution. The advent of magnetic devices, such as the compass and much later, magnetic storage devices, allowed for the creation of far more accurate maps and the ability to store and manipulate them digitally . Advances in mechanical devices such as

11520-792: The diminished proportions of those regions compared to higher latitudes where the European powers were concentrated. Maps furthered imperialism and colonization of Africa in practical ways by showing basic information like roads, terrain, natural resources, settlements, and communities. Through this, maps made European commerce in Africa possible by showing potential commercial routes and made natural resource extraction possible by depicting locations of resources. Such maps also enabled military conquests and made them more efficient, and imperial nations further used them to put their conquests on display. These same maps were then used to cement territorial claims, such as at

11664-674: The dominant Chinese structure, rather than being forcibly subjugated. For instance, the aboriginal chief Lady Xian who married the Liang court's governor Feng Bao, helped to extend the dynasties' authority while preserving autonomy and local culture. Lady Xian and Feng Bao played a critical role in assisting Chen Baxian's rise, and in stabilising the region between the Liang, Chen, and Sui dynasties. The court acknowledged her authority by awarding her with official titles and emblems of power. There were many other local chieftains of mixed origins between Guangzhou and modern Vietnam that displayed mixed traits of both aboriginal and sinicized culture, such as

11808-432: The double hemisphere being very common and Mercator's prestigious navigational projection gradually making more appearances. Due to the paucity of information and the immense difficulty of surveying during the period, mapmakers frequently plagiarized material without giving credit to the original cartographer. For example, a famous map of North America known as the "Beaver Map" was published in 1715 by Herman Moll . This map

11952-523: The dynasty, known in historiography as the Eastern Jin dynasty . Cementing their power in the south, the Eastern Jin established Jiankang on the existing site of Jianye (now Nanjing ) as their new capital. In the north, the Five Barbarians established numerous short-lived dynasties, leading to the period known as the Sixteen Kingdoms in historiography. Eventually, the Northern Wei dynasty conquered

12096-475: The early seventeenth century, the Selden map was created by a Chinese cartographer. Historians have put its date of creation around 1620, but there is debate in this regard. This map's significance draws from historical misconceptions of East Asian cartography, the main one being that East Asians did not do cartography until Europeans arrived. The map's depiction of trading routes, a compass rose, and scale bar points to

12240-497: The empress dowager and the young emperor thrown into the Yellow River while establishing his own puppet ruler to maintain authority. As conflict swelled in the north between successive leaders, Gao Huan took control of the east and Luoyang (holding Emperor Xiaojing of Eastern Wei as a puppet ruler) by 534, while his rival Yuwen Tai took control of the west and the traditional Chinese capital of Chang'an by 535. The Western regime

12384-526: The equator; and the Bonne projection is intermediate between the two. In 1569, mapmaker Gerardus Mercator first published a map based on his Mercator projection , which uses equally-spaced parallel vertical lines of longitude and parallel latitude lines spaced farther apart as they get farther away from the equator. By this construction, courses of constant bearing are conveniently represented as straight lines for navigation. The same property limits its value as

12528-505: The field of cartography can be divided into two general categories: general cartography and thematic cartography. General cartography involves those maps that are constructed for a general audience and thus contain a variety of features. General maps exhibit many reference and location systems and often are produced in a series. For example, the 1:24,000 scale topographic maps of the United States Geological Survey (USGS) are

12672-399: The founding elites of the Sui and Tang dynasties. Hence, they tended to have a flexible approach to steppe nomads, viewing them as possible partners rather than intrinsic enemies. The Jin were succeeded by a series of short-lived dynasties: Liu Song (420–479), Southern Qi (479–502), Liang (502–557) and Chen (557–589). As all of these dynasties had their capital at Jiankang (except for

12816-424: The general public or as narrow as a single person. Mapmakers use design principles to guide them in constructing a map that is effective for its purpose and audience. The cartographic process spans many stages, starting from conceiving the need for a map and extending all the way through its consumption by an audience. Conception begins with a real or imagined environment. As the cartographer gathers information about

12960-513: The government secretaries, he slaughtered all the sons of Emperors Gao and Wu. Emperor Ming soon became very ill and started following Daoism, changing his whole wardrobe to red. He also passed an edict making officials try to find whitebait (銀魚). He died in 498 and was succeeded by his son Xiao Baojuan , who killed high officials and governors at whim, sparking many revolts. The final revolt in 501 started after Xiao Baojuan killed his prime minister Xiao Yi, leading his brother Xiao Yan to revolt under

13104-506: The imperial clan, one of which saw him slaughter the inhabitants of Guangling . The following ballad gives an idea of those times: Emperor Xiaowu died naturally in 464 and was succeeded by his son, who became Emperor Qianfei . Emperor Qianfei proved to be similar to his father, engaging in both kin-slaughter and incest. In a scandalous move, because his sister complained about how it was unfair that men were allowed 10,000 concubines, he gave her 30 handsome young men as lovers. His uncle Liu Yu,

13248-425: The lost territories south of the Huai River. In 573, he sent general Wu Mingche to assist the effort; in two years, he managed to recover he lost territories south of the Huai River. At the time, Northern Qi was in a precarious situation with little military strength and Emperor Xuan could have taken advantage of the opportunity to entirely defeat Northern Qi. However, he only wanted to protect his territories south of

13392-604: The making of maps. The ability to superimpose spatially located variables onto existing maps has created new uses for maps and new industries to explore and exploit these potentials. See also digital raster graphic . In the early years of the new millennium, three key technological advances transformed cartography: the removal of Selective Availability in the Global Positioning System (GPS) in May 2000, which improved locational accuracy for consumer-grade GPS receivers to within

13536-448: The most accurate world map for the next three centuries. The map was divided into seven climatic zones, with detailed descriptions of each zone. As part of this work, a smaller, circular map depicting the south on top and Arabia in the center was made. Al-Idrisi also made an estimate of the circumference of the world, accurate to within 10%. In the Age of Discovery , from the 15th century to

13680-554: The most highly decorated of the Yungang Grottoes , and had a temple constructed in 488 at Lirun, Fengyi (modern day Chengcheng), which was his birthplace according to the Booke of Wei. Wang Yu may have been castrated during the suppression of a 446 Qiang rebellion since the Northern Wei would castrate rebel tribes' young elite. In the first half of the Northern Wei dynasty , the Xianbei steppe tribesmen who dominated northern China kept

13824-562: The nearby areas. The rest of the Liang dynasty lands were under the control of members of the imperial clan. Their squabbling amongst themselves weakened their efforts to defeat Hou. In the end, Xiao Yi with the aid of his generals Wang Sengbian and Chen Baxian defeated Hou, crowning himself Emperor Yuan of Liang . His brother Xiao Ji based in Sichuan was still a major threat. Emperor Yuan asked for assistance from Western Wei to defeat Xiao Ji, but after subduing Xiao Ji, they kept Sichuan. Due to

13968-432: The north forced them to divert their focus from their southern expeditions. After uniting the north, Emperor Taiwu also conquered the powerful Shanshan kingdom and subjugated the other kingdoms of Xiyu ( Western Regions ). In 450, Emperor Taiwu once again attacked the Liu Song and reached Guabu (瓜步, in modern Nanjing, Jiangsu), threatening to cross the river to attack Jiankang, the Liu Song capital. Though up to this point,

14112-445: The only route to cartographic truth…". A common belief is that science heads in a direction of progress, and thus leads to more accurate representations of maps. In this belief, European maps must be superior to others, which necessarily employed different map-making skills. "There was a 'not cartography' land where lurked an army of inaccurate, heretical, subjective, valuative, and ideologically distorted images. Cartographers developed

14256-415: The paper is depressed compared to the margins. Copper and other metals were expensive at the time, so the plate was often reused for new maps or melted down for other purposes. Whether woodcut or intaglio, the printed map is hung out to dry. Once dry, it is usually placed in another press to flatten the paper. Any type of paper that was available at the time could be used to print the map, but thicker paper

14400-653: The period include the mathematician and astronomer Zu Chongzhi (429–500), and astronomer Tao Hongjing . After the collapse of a unified China proper under the Eastern Han dynasty in 220 due in large part to the Yellow Turban and the Five Pecks of Rice rebellions, China eventually coalesced into the Three Kingdoms . Of these, Cao Wei was the strongest, followed by Eastern Wu and Shu Han , but they were initially in

14544-507: The period was called the Reign of Yuanjia ( Chinese : 元嘉之治 ). In 430, Emperor Wen started a number of northern expeditions against Northern Wei. These were ineffective because of insufficient preparations and excessive micromanagement of his generals, increasingly weakening the dynasty. Because of his jealousy of Tan Daoji , a noted leader of the Army of the Northern Garrison, he deprived himself of

14688-582: The pretender Yuan Hao . Despite the fact that Chen was only given 7,000 troops, he still managed to defeat army after army and even captured Luoyang, the capital of Northern Wei. Ultimately, Chen was insufficiently supplied and was defeated by troops ten times his size. After the Northern Wei split into Eastern and Western Wei, Emperor Wu granted asylum to rebel Eastern Wei commander Hou Jing , sending him on Northern Expeditions against Eastern Wei. After some initial successes, Liang forces were decisively defeated. Rumors abounded that Emperor Wu intended to give Hou as

14832-435: The primary power brokers in the Eastern Jin. With the greatly increased importance of proving one's pedigree to receive privileges, there was a rise in compiling of genealogy records, and the great families moved to legally outlaw intermarriage with common families. The lower class Northern migrants were forced to become "guests" (dependents) of the great families who established private guard forces with their new retainers. When

14976-492: The prints rather than having to create a new one. On the other hand, it is hard to achieve fine detail with the relief technique. Inconsistencies in linework are more apparent in woodcut than in intaglio. To improve quality in the late fifteenth century, a style of relief craftsmanship developed using fine chisels to carve the wood, rather than the more commonly used knife. In intaglio, lines are engraved into workable metals, typically copper but sometimes brass. The engraver spreads

15120-424: The produce of their estates, the resurgence of trade and the money-based economy forced them to break up and sell their lands to the burgeoning merchant class. Influential merchants increasingly occupied political offices, displacing the old aristocrats. On the other hand, the economic developments also drove peasants, unable to cope with inflation or to pay taxes in cash, to become mercenary soldiers, wandering through

15264-721: The range of applications for cartography, for example in the development of satnav devices. Today most commercial-quality maps are made using software of three main types: CAD , GIS and specialized illustration software . Spatial information can be stored in a database , from which it can be extracted on demand. These tools lead to increasingly dynamic, interactive maps that can be manipulated digitally. Field-rugged computers , GPS , and laser rangefinders make it possible to create maps directly from measurements made on site. There are technical and cultural aspects to producing maps. In this sense, maps can sometimes be said to be biased. The study of bias, influence, and agenda in making

15408-608: The region of Wu (a region near modern-day Shanghai). At that time, due to the Hou Jing rebellion, the Qiao and Wu clans were greatly weakened, and many independent regimes emerged. Emperor Wu could not pacify all the independent regimes, so he adopted conciliatory measures. After the sudden death of Emperor Wu, his nephew Chen Qian took power as Emperor Wen of Chen . After the fall of Liang, the general Wang Lin had established an independent kingdom based in modern-day Hunan and Hubei provinces and

15552-434: The rest of the northern states in 439 and unified northern China. Although the Eastern Jin and successive southern dynasties were well-defended from the northern dynasties by their placement of naval fleets along the Yangtze, they suffered various problems related to the creation and maintenance of military strength. The court's designation of specific households for military service through the tuntian system eventually led to

15696-503: The rise and usurpation of the Sima family who established the Jin dynasty; subsequent leaders were similarly unable to bring the other great families in line. The Jin dynasty's flight south greatly exacerbated the weakness of the central government, and the great families who accompanied the Emperor in his flight, along with the most wealthy clans of earlier settlers along the Zhejiang coast, were

15840-408: The sheet. Being raised from the rest of the block, the map lines cause indentations in the paper that can often be felt on the back of the map. There are advantages to using relief to make maps. For one, a printmaker doesn't need a press because the maps could be developed as rubbings. Woodblock is durable enough to be used many times before defects appear. Existing printing presses can be used to create

15984-472: The sixteenth century, maps were becoming increasingly available to consumers through the introduction of printmaking, with about 10% of Venetian homes having some sort of map by the late 1500s. There were three main functions of maps in the Renaissance: In medieval times, written directions of how to get somewhere were more common than the use of maps. With the Renaissance, cartography began to be seen as

16128-512: The south went from being nearly a frontier to being on a path to the thriving, urbanized, sinicized region that it became in later centuries. In his book Buddhism in Chinese History , Arthur F. Wright points out this fact by stating: "When we speak of the area of the Yangtze valley and below in the period of disunion, we must banish from our minds the picture of the densely populated, intensively cultivated South China of recent centuries. When

16272-453: The spread of Mahayana Buddhism and Taoism . The period saw large-scale migration of Han people to lands south of the Yangtze . The period came to an end with the unification of China proper by Emperor Wen of the Sui dynasty . During this period, the process of sinicization accelerated among the non-Han ethnicities in the north and among the indigenous peoples in the south. This process

16416-480: The strength of the Northern Wei, who suffered internal strife due to their policy of sinicization . In 503, the Northern Wei invaded but were defeated at Zhongli (modern Bengbu ). Emperor Wu supported the Northern Expeditions but did not aggressively take advantage of his victory in 516 at Shouyang due to heavy casualties. Given the excessive kin-slaughter in the Liu Song and Southern Qi dynasties, Emperor Wu

16560-404: The subject, they consider how that information is structured and how that structure should inform the map's design. Next, the cartographers experiment with generalization , symbolization , typography , and other map elements to find ways to portray the information so that the map reader can interpret the map as intended. Guided by these experiments, the cartographer settles on a design and creates

16704-441: The throne. This stopped the southern advance of the northern troops. The respite was short though, as after Yang Jian defeated his rival General Yuchi Jiong , he usurped the throne from Emperor Jing of Northern Zhou and established the Sui dynasty , crowning himself Emperor Wen of Sui . He proceeded to invade the south to reunify China. Emperor Xuan had just died and his incompetent son Chen Shubao (Houzhu of Chen) took power. He

16848-550: The time of Anaximander in the 6th century BCE. In the 2nd century CE, Ptolemy wrote his treatise on cartography, Geographia . This contained Ptolemy's world map – the world then known to Western society ( Ecumene ) . As early as the 8th century, Arab scholars were translating the works of the Greek geographers into Arabic. Roads were essential in the Roman world, motivating the creation of maps, called itinerarium , that portrayed

16992-459: The troubles of a coarse medium and so was able to express the looping cursive that came to be known as cancellaresca . There were custom-made reverse punches that were also used in metal engraving alongside freehand lettering. The first use of color in map-making cannot be narrowed down to one reason. There are arguments that color started as a way to indicate information on the map, with aesthetics coming second. There are also arguments that color

17136-513: The warring princes heavily drafted these tribes into the military, they mutinied and exploited the civil wars to seize power. Their armies almost destroyed the dynasty in the Disaster of Yongjia of 311, when the Five Barbarians sacked Luoyang . Chang'an met a similar fate in 316. However, a scion of the imperial house, Sima Rui (Emperor Yuan of Jin) fled south of the Huai River and reestablished

17280-611: The world as experienced via the roads. The Tabula Peutingeriana is the only surviving example. In ancient China , geographical literature dates to the 5th century BCE. The oldest extant Chinese maps come from the State of Qin , dated back to the 4th century BCE, during the Warring States period . In the book Xin Yi Xiang Fa Yao , published in 1092 by the Chinese scientist Su Song ,

17424-505: The world from the Earth's creation by God until 1568. He was unable to complete it to his satisfaction before he died. Still, some additions were made to the Atlas after his death, and new editions were published after his death. In 1570, the Brabantian cartographer Abraham Ortelius , strongly encouraged by Gillis Hooftman , created the first true modern atlas, Theatrum Orbis Terrarum . In

17568-458: The world') are the medieval European maps of the world. About 1,100 of these are known to have survived: of these, some 900 are found illustrating manuscripts, and the remainder exist as stand-alone documents. The Arab geographer Muhammad al-Idrisi produced his medieval atlas Tabula Rogeriana (Book of Roger) in 1154. By combining the knowledge of Africa , the Indian Ocean , Europe , and

17712-584: The year 495 to serve in the capital. Within a couple of decades, the population rose to about half a million residents and was famed for being home to over a thousand Buddhist temples. Defectors from the south, such as Wang Su of the prestigious Langye Wang family, were largely accommodated and felt at home with the establishment of their own Wu quarter in Luoyang (this quarter of the city was home to over three thousand families). They were even served tea (by this time gaining popularity in southern China) at court instead of

17856-506: The year 523, Prince Dongyang of the Northern Wei was sent to Dunhuang to serve as its governor for a term of fifteen years. With Buddhism gaining mainstream acceptance in Chinese society, Prince Dongyang and local wealthy families set out to establish a monumental project in honor of Buddhism, carving and decorating Cave 285 of the Mogao Caves with beautiful statues and murals. Such promotion of

18000-481: The yogurt drinks commonly found in the north. Beginning in the 480s, the Northern Wei arranged for Han elites to marry daughters of the Xianbei Tuoba imperial family. More than fifty per cent of Tuoba Xianbei princesses of the Northern Wei were married to southern Han men from the imperial families and aristocrats of the southern dynasties, who defected and moved north to join the Northern Wei. Several daughters of

18144-552: Was 16th in a 2010 ranking of China's top county-level cities. Businesses from 32 countries and regions have invested in Danyang with accumulated paid-in capital of US$ 1 billion. As a developing city within the Shanghai economic sphere of influence, Danyang has attracted domestic and foreign businesses. The main industries in Danyang are prescription eyewear, tools and hardware, and automobile parts. The Spectacles City , located in Danyang,

18288-463: Was a Xianbei, but whose mother was Han. Although of the Tuoba Clan from the Xianbei tribe, Emperor Xiaowen asserted his dual Xianbei-Han identity, renaming his own clan "Yuan" ( 元 ). In the year 493 Emperor Xiaowen instituted a new sinification program that had the Xianbei elites conform to many Han standards. These social reforms included donning Han clothing (banning Xianbei clothing at court), learning

18432-520: Was a decadent ruler who had lost the Mandate of Heaven , the Sui Dynasty was able to effectively conquer the south. After this conquest, the whole of China entered a new golden age of reunification under the centralization of the short-lived Sui dynasty and the succeeding Tang dynasty (618–907). The core elite of the Northern dynasties, mixed-culture, and mixed-ethnicity military clans, would later also form

18576-416: Was a period of political division in the history of China that lasted from 420 to 589, following the tumultuous era of the Sixteen Kingdoms and the Eastern Jin dynasty . It is sometimes considered as the latter part of a longer period known as the Six Dynasties (220–589). The period featured civil war and political chaos, but was also a time of flourishing arts and culture, advancement in technology, and

18720-473: Was afraid they would have thoughts of usurping the throne. Thus, he also frequently killed his kinsmen. After the death of Emperor Wu, his son Emperor Shao ruled briefly before being judged incompetent and killed by government officials led by Xu Xianzhi , replacing him with Emperor Wen , a different son, who soon killed the officials who supported him. Emperor Wen's reign was a period of relative political stability because of his frugality and good government;

18864-508: Was also accompanied by the increasing popularity of Buddhism in both northern and southern China and Daoism gaining influence as well, with two essential Daoist canons written during this period. Notable technological advances occurred during this period. The invention of the stirrup during the earlier Jin dynasty (266–420) helped spur the development of heavy cavalry as a combat standard. Historians also note advances in medicine, astronomy , mathematics , and cartography . Intellectuals of

19008-580: Was dominated by the sinicized nobles and their Han bureaucrats while the Eastern regime was controlled by the traditional steppe tribes. Eventually, Gao Huan's son Gao Yang forced the Eastern Wei emperor to abdicate in favor of his claim to the throne, establishing the Northern Qi dynasty (551–577). Afterward, Yuwen Tai's son Yuwen Jue seized the throne of power from Emperor Gong of Western Wei , establishing

19152-522: Was first used on maps for aesthetics but then evolved into conveying information. Either way, many maps of the Renaissance left the publisher without being colored, a practice that continued all the way into the 1800s. However, most publishers accepted orders from their patrons to have their maps or atlases colored if they wished. Because all coloring was done by hand, the patron could request simple, cheap color, or more expensive, elaborate color, even going so far as silver or gold gilding. The simplest coloring

19296-411: Was highly successful in boosting the state's military strength. The Northern Zhou dynasty was able to defeat and conquer Northern Qi in 577, reunifying the north. However, this success was short-lived, as the Northern Zhou was overthrown in 581 by Yang Jian, who became Emperor Wen of Sui . With greater military power and morale, along with convincing propaganda that the Chen dynasty ruler Chen Shubao

19440-451: Was in a weakened state. Emperor Wen was assassinated by Crown Prince Shao and Second Prince Jun in 453 after planning to punish them for witchcraft. However, they were both defeated by Third Prince Jun, who become Emperor Xiaowu . proved to be licentious and cruel, supposedly committing incest with the daughters of an uncle who had helped him gain the throne; his rivals also claimed he had incest with his mother. This led to two rebellions by

19584-547: Was licentious and wasteful, resulting in chaos and corruption in the government; many officials heavily exploited the people, causing great suffering. In planning to defeat the Chen dynasty, Emperor Wen of Sui took the suggestion of his general Gao Jiong and waited until the South were harvesting their crops to entirely burn the farmland, crippling the strength of the Chen dynasty. In 588, Emperor Wen of Sui sent his son Yang Guang (who would become Emperor Yang of Sui ) to finally vanquish

19728-408: Was merely outlines, such as of borders and along rivers. Wash color meant painting regions with inks or watercolors. Limning meant adding silver and gold leaf to the map to illuminate lettering, heraldic arms, or other decorative elements. The early modern period saw the convergence of cartographical techniques across Eurasia and the exchange of mercantile mapping techniques via the Indian Ocean. In

19872-489: Was more durable. Both relief and intaglio were used about equally by the end of the fifteenth century. Lettering in mapmaking is important for denoting information. Fine lettering is difficult in woodcut, where it often turned out square and blocky, contrary to the stylized, rounded writing style popular in Italy at the time. To improve quality, mapmakers developed fine chisels to carve the relief. Intaglio lettering did not suffer

20016-493: Was not given the imperial title. After some defeats to the forces of Northern Qi, Wang Sengbian allowed their pretender, Xiao Yuanming to establish himself as Emperor Min of Liang. However, Chen Baxian was displeased with the arrangements, and in a surprise move killed Wang and deposed Emperor Min in favor of Xiao Fangzhi who became Emperor Jing of Liang. After a short reign, Chen deposed Emperor Jing and took power himself as Emperor Wu of Chen in 557. Emperor Wu of Chen came from

20160-475: Was now starting to cause trouble. Wang Lin allied with Northern Zhou and Northern Qi to conquer the Chen capital at Jiankang. Emperor Wen first defeated the combined forces of Northern Qi and Wang Lin before preventing the forces of Northern Zhou from entering the South at Yueyang . Furthermore, through Emperor Wen's extensive efforts at good governance, the economic situation of the South was greatly improved, restoring his kingdom's national strength. Following

20304-599: Was overtaken by atlas makers in the late 16th century. Map publishing in Venice was completed with humanities and book publishing in mind, rather than just informational use. There were two main printmaking technologies in the Renaissance: woodcut and copper-plate intaglio , referring to the medium used to transfer the image onto paper. In woodcut, the map image is created as a relief chiseled from medium-grain hardwood. The areas intended to be printed are inked and pressed against

20448-456: Was the most notable ruler of his age, being a patron of the arts and of Buddhism. The Southern dynasties, except for the last Chen dynasty, were strongly dominated by the shijia , the great families, who monopolized political power until the mid-6th century. This class was created by Cao Cao during the late Han dynasty when he attempted to consolidate his power by building an endogenous military caste of professional soldiers. His policy led to

20592-522: Was very lenient to imperial clansmen, not even investigating them when they committed crimes. The Liang reached a cultural peak because he was very learned, supported scholars, and encouraged the flourishing education system. An avid poet, Emperor Wu was fond of gathering many literary talents at court, and even held poetry competitions with prizes of gold or silk for those considered the best. In his later years, however, sycophants surrounded him. Three times he dedicated his life to Buddhism and tried to become

20736-415: Was volatile. General Xiao Daocheng slowly gained power and eventually deposed Emperor Houfei in favor of his brother, who became Emperor Shun . After defeating the rival general Shen Youzhi , Xiao forced Emperor Shun to yield the throne and crowned himself Emperor Gao of Southern Qi , thus ending the Liu Song dynasty. Though distantly related, the Southern Qi and the following Liang dynasty were members of
