Cartography ( / k ɑːr ˈ t ɒ ɡ r ə f i / ; from Ancient Greek : χάρτης chartēs , 'papyrus, sheet of paper, map'; and γράφειν graphein , 'write') 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.
102-616: Andreas Cellarius ( c. 1596 –1665) was a Dutch–German cartographer and cosmographer best known for his 1660 Harmonia Macrocosmica , a major star atlas . He was born in Neuhausen , and was educated in Heidelberg . The Protestant Cellarius may have left Heidelberg at the onset of the Thirty Years' War in 1618 or in 1622, when the city came into Catholic hands. His activities are unclear at this time, but based on his later works, it
204-591: 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
306-532: 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
408-438: A 'horizontal' or east–west alliance called lianheng ( 連橫{ ), in which a state would ally with Qin to participate in its ascendancy. There were some initial successes in hezong , though mutual suspicions between allied states led to the breakdown of such alliances. Qin repeatedly exploited the horizontal alliance strategy to defeat the states one by one. During this period, many philosophers and tacticians travelled around
510-530: 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
612-463: A calming effect on Qi's own population, which experienced great domestic tranquility during Wei's reign. By the end of King Wei's reign, Qi had become the strongest of the states and proclaimed itself "king"; establishing independence from the Zhou dynasty (see below). King Hui of Wei (370–319 BC) set about restoring the state. In 362–359 BC he exchanged territories with Han and Zhao in order to make
714-428: 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
816-399: 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
918-482: 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
1020-540: A few states gaining power at the expense of many others, the latter no longer able to depend on central authority for legitimacy or protection. During the Warring States period, many rulers claimed the Mandate of Heaven to justify their conquest of other states and spread their influence. The struggle for hegemony eventually created a state system dominated by several large states, such as Jin , Chu, Qin, Yan, and Qi, while
1122-408: 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

#17328771929051224-404: A good relationship with his Qi counterpart, with both promising to recognize the other as "king". Early in the Warring States period, Chu was one of the strongest states in China. The state rose to a new level of power around 389 BC when King Dao of Chu ( 楚悼王 ) named the famous reformer Wu Qi as his chancellor. Chu rose to its peak in 334 BC, when it conquered Yue to its east on
1326-413: A great defeat at the hands of Qin. King Kao of Zhou had enfeoffed his younger brother as Duke Huan of Henan. Three generations later, this cadet branch of the royal house began calling themselves "dukes of East Zhou". Upon the ascension of King Nan in 314, East Zhou became an independent state. The king came to reside in what became known as West Zhou. Towards the end of the Warring States period,
1428-576: 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
1530-441: 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
1632-431: 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
1734-575: 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
1836-456: A period of shifting alliances and wars on several fronts. In 376 BC, the states of Han, Wei and Zhao deposed Duke Jing of Jin and divided the last remaining Jin territory between themselves, which marked the final end of the Jin state. In 370 BC, Marquess Wu of Wei died without naming a successor, which led to a war of succession. After three years of civil war, Zhao from the north and Han from
1938-460: 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
2040-520: A son of King Hui by a concubine (i.e. a younger half-brother of King Wu) could be established as King Zhao , who in stark contrast to his predecessor went on to rule for an unprecedented 53 years. After the failure of the first vertical alliance, Su Qin eventually came to live in Qi, where he was favored by King Xuan and drew the envy of the ministers. An assassination attempt in 300 BC left Su mortally wounded but not dead. Sensing death approaching, he advised
2142-531: 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

#17328771929052244-515: A succession struggle in 307, yielded to the new coalition and appointed Lord Mengchang its chief minister. The alliance between Qin and Qi was sealed by a Qin princess marrying King Min. This horizontal or east–west alliance might have secured peace except that it excluded the State of Zhao . Around 299 BC, the ruler of Zhao became the last of the seven major states to proclaim himself "king". In 298 BC, Zhao offered Qin an alliance and Lord Mengchang
2346-416: 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
2448-400: 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
2550-399: A young age and passed tax laws to encourage raising multiple children. He also enacted policies to free convicts who worked in opening wastelands for agriculture. Shang abolished primogeniture and created a double tax on households that had more than one son living in the household, to break up large clans into nuclear families. Shang also moved the capital to reduce the influence of nobles on
2652-450: 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
2754-467: 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
2856-681: Is conjectured that he spent time in Poland where he may have worked as a military engineer. In 1625, he married Catharina Eltemans in Amsterdam , where he worked as a schoolmaster at a Latin school. After a brief stay in The Hague , the family moved to Hoorn . From 1637 until his death, he was rector of the Latin School in Hoorn, where Pieter Anthoniszoon Overtwater was conrector. The minor planet 12618 Cellarius
2958-456: 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
3060-401: Is named in his honour. This article about a Dutch artist is a stub . You can help Misplaced Pages by expanding it . Cartographer 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).

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
3366-556: The Record of the Warring States , a work of history compiled during the early Han dynasty (202 BC – 220 AD). The political geography of the era was dominated by the Seven Warring States , namely: Besides these seven major states other smaller states survived into the period. They include: The eastward flight of the Zhou court in 771 BC marks the start of
3468-580: The Battle of Maling . After the battle all three of the Jin successor states appeared before King Xuan of Qi , pledging their loyalty. In the following year Qin attacked the weakened Wei. Wei was devastatingly defeated and ceded a large part of its territory in return for truce. With Wei severely weakened, Qi and Qin became the dominant states in China. Wei came to rely on Qi for protection, with King Hui of Wei meeting King Xuan of Qi on two occasions. After Hui's death, his successor King Xiang also established
3570-548: 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,

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
3774-512: 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
3876-737: 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
3978-798: The Spring and Autumn period . No one single incident or starting point inaugurated the Warring States era. The political situation of the period represented a culmination of historical trends of conquest and annexation which also characterised the Spring and Autumn period. As a result, there is some controversy as to the beginning of the era. Proposed starting points include: The Eastern Zhou dynasty began its fall around 5th century BC. As their influence waned, they had to rely on armies in allied states rather than their own military force. Hundreds of smaller polities coalesced into seven major states which included: Chu, Han, Qin, Wei, Yan, Qi and Zhao. However, there eventually
4080-569: 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
4182-477: 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

4284-451: The state of Qin became disproportionately powerful compared with the other six states. As a result, the policies of the six states became overwhelmingly oriented towards dealing with the Qin threat, with two opposing schools of thought. One school advocated a 'vertical' or north–south alliance called hezong ( 合縱 ) in which the states would ally with each other to repel Qin. The other advocated
4386-472: 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
4488-517: 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
4692-546: The Earth. In 1507, Martin Waldseemüller produced a globular world map and a large 12-panel world wall map ( Universalis Cosmographia ) bearing the first use of the name "America." Portuguese cartographer Diogo Ribero was the author of the first known planisphere with a graduated Equator (1527). Italian cartographer Battista Agnese produced at least 71 manuscript atlases of sea charts. Johannes Werner refined and promoted
4794-509: The Pacific coast. The series of events leading up to this began when Yue prepared to attack Qi to its north. The King of Qi sent an emissary who persuaded the King of Yue to attack Chu instead. Yue initiated a large-scale attack at Chu but was defeated by Chu's counter-attack. Chu then proceeded to conquer Yue. King Xian of Zhou had attempted to use what little royal prerogative he had left by appointing
4896-650: The Space Oblique Mercator for interpreting satellite ground tracks for mapping the surface. The use of satellites and space telescopes now allows researchers to map other planets and moons in outer space. Advances in electronic technology ushered in another revolution in cartography: ready availability of computers and peripherals such as monitors, plotters, printers, scanners (remote and document) and analytic stereo plotters, along with computer programs for visualization, image processing, spatial analysis, and database management, have democratized and greatly expanded
4998-429: The Zhou court. This marked a major turning point: unlike those in the Spring and Autumn period , the new generation of rulers ascending the thrones in the Warring States period would not entertain even the pretence of being vassals of the Zhou dynasty, instead proclaiming themselves fully independent kingdoms. During the early Warring States period Qin generally avoided conflicts with the other states. This changed during
5100-544: The administration. The rise of Qin was recognized by the royal court, and in 343 BC the king conferred the title of Count (伯 Bó) on Duke Xiao. As was customary, a conference was hosted which the feudal lords attended, and during which the Son of Heaven bestowed the title. After the reforms Qin became much more aggressive. In 340 Qin took land from Wèi after it had been defeated by Qi. In 316 Qin conquered Shu and Ba in Sichuan to
5202-449: The alliance. In 383 BC it moved its capital to Handan and attacked the small state of Wey . Wey appealed to Wei which attacked Zhao on the western side. Being in danger, Zhao called in Chu. As usual, Chu used this as a pretext to annex territory to its north, but the diversion allowed Zhao to occupy a part of Wei. This conflict marked the end of the power of the united Jins and the beginning
SECTION 50
#17328771929055304-507: The beginning of the Warring States period, Sima Qian 's choice of 475 BC is the most often cited. The era largely corresponds to the second half of the Eastern Zhou period, where the king of Zhou formally ruled as Chinese sovereign , but had lost political power and functioned in practice as a figurehead. This dynamic served as the backdrop for the machinations of the eponymous Warring States. The label "Warring States period" derives from
5406-515: The boundaries of the three states more rational. In 364 BC, Wei was defeated by Qin at the Battle of Shimen and was only saved by the intervention of Zhao. Qin won another victory in 362 BC. In 361 BC the Wei capital was moved east to Daliang to be out of the reach of Qin. In 354 BC, King Hui of Wei started a large-scale attack on Zhao. By 353 BC, Zhao was losing badly and its capital, Handan ,
5508-496: 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
5610-433: 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
5712-792: 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
5814-484: The diplomat Su Qin spent years visiting the courts of Yan, Zhao, Han, Wei, Qi and Chu and persuaded them to form a united front against Qin. In 318 BC all states except Qi launched a joint attack on Qin, which was not successful. King Hui of Qin died in 311 BC, followed by prime minister Zhang Yi one year later. The new monarch, King Wu , reigned only four years before dying without legitimate heirs. Some damaging turbulence ensued throughout 307 BC before
5916-432: 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
6018-401: The dukes Xian (384–362 BC), Xiao (361–338 BC) and Hui (338–311 BC) of Qin as hegemons, thereby in theory making Qin the chief ally of the court. However, in 325 the confidence of Duke Hui grew so great that he proclaimed himself "king" of Qin; adopting the same title as the king of Zhou and thereby effectively proclaiming independence from the Zhou dynasty. King Hui of Qin
6120-475: 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
6222-459: The end of Jiang rule, and now openly assumed power. The new ruler set about reclaiming territories that had been lost to other states. He launched a successful campaign against Zhao, Wey and Wei, once again extending Qi territory to the Great Wall. Sima Qian writes that the other states were so awestruck that nobody dared attack Qi for more than 20 years. The demonstrated military prowess also had

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
6426-524: The establishment of four major families, the Han, Zhao, Wei and Zhi. The Battle of Jinyang saw the allied Han, Zhao and Wei destroy the Zhi family (453 BC) and their lands were distributed among them. With this, they became the de facto rulers of most of Jin's territory, though this situation would not be officially recognised until half a century later. The Jin division created a political vacuum that enabled during
6528-505: 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

It followed the Spring and Autumn period and concluded with the wars of conquest that saw the state of Qin annex each of the other contender states by 221 BC and found the Qin dynasty , the first imperial dynastic state in East Asian history. While scholars have identified several different dates as marking
6732-411: The first 50 years expansion of Chu and Yue northward and Qi southward. Qin increased its control of the local tribes and began its expansion southwest to Sichuan . In 403 BC, the court of King Weilie of Zhou officially recognized Zhao, Wei and Han as immediate vassals, thereby raising them to the same rank as the other warring states. From before 405 until 383 BC the three Jins were united under
6834-424: 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

In 408–406 BC he conquered the State of Zhongshan to the northeast on the other side of Zhao. At the same time he pushed west across the Yellow River to the Luo River taking the area of Xihe (literally 'west of the [Yellow] river'). The growing power of Wei caused Zhao to back away from

King Min complied with Su's request and killed him, putting an end to the first generation of Vertical alliance thinkers. King Min of Qi came to be highly influenced by Lord Mengchang , a grandson of the former King Wei of Qi . Lord Mengchang made a westward alliance with the states of Wei and Han . In the far west, Qin, which had been weakened by
7446-445: 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
7548-415: 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

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
7752-721: 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
7854-415: The reign of Duke Xiao , when prime minister Shang Yang made centralizing and authoritarian reforms in accordance with his Legalist philosophy between the years 356 and 338 BC. Shang introduced land reforms, privatized land, rewarded farmers who exceeded harvest quotas, enslaved farmers who failed to meet quotas, and used enslaved subjects as rewards for those who met government policies. As manpower
7956-408: 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
8058-472: 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
8160-464: The smaller states of the Central Plain tended to be their satellites and tributaries. Other major states also existed, such as Wu and Yue in the southeast. The last decades of the Spring and Autumn era were marked by increased stability, as the result of peace negotiations between Jin and Chu which established their respective spheres of influence. This situation ended with the partition of Jin, whereby
8262-452: The south invaded Wei. On the verge of conquering Wei, the leaders of Zhao and Han fell into disagreement about what to do with Wei, and both armies abruptly retreated. As a result, King Hui of Wei (still a Marquess at the time) was able to ascend the throne of Wei. Zhao extended from the Shanxi plateau across the plain to the borders of Qi. Wei reached east to Qi, Lu , and Song . To the south,
8364-447: The southwest. Development of this area took a long time but slowly added greatly to Qin's wealth and power. In 341 BC, Wei attacked Han. Qi allowed Han to be nearly defeated and then intervened. The generals from the Battle of Guiling met again ( Sun Bin and Tian Ji versus Pang Juan ), using the same tactic, attacking Wei's capital. Sun Bin feigned a retreat and then turned on the overconfident Wei troops and decisively defeated them at
8466-489: The state was divided between the houses of Han, Zhao and Wei, leading to the seven major warring states. The rulers of Jin had steadily lost political powers since the middle of the 6th century BC to their nominally subordinate nobles and military commanders, a situation arising from the traditions of the Jin which forbade the enfeoffment of relatives of the ducal house. This allowed other clans to gain fiefs and military authority, and decades of internecine struggle led to
8568-483: The states, recommending that the rulers put their respective ideas into use. These "lobbyists", such as Su Qin , who advocated vertical alliances, and Zhang Yi , who advocated horizontal alliances, were famous for their tact and intellect, and were collectively known as the School of Diplomacy , whose Chinese name ( 縱橫家 'the school of the vertical and horizontal') was derived from the two opposing ideas. Beginning in 334 BC
8670-404: 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
8772-550: 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
8874-459: 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
8976-423: The weaker state of Han held the east–west part of the Yellow River valley, surrounded the Zhou royal domain at Luoyang and held an area north of Luoyang called Shangdang . Duke Kang of Qi died in 379 BC with no heir from the house of Jiang, which had ruled Qi since the state's founding. The throne instead passed to the future King Wei , from the house of Tian. The Tian had been very influential at court towards
9078-515: 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 ,
9180-505: 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
9282-458: 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
9384-506: Was a shift in alliances because each state's ruler wanted independence. This caused hundreds of wars between 535 and 286 BC. The victorious state would have overall rule and control in China. The system of feudal states created by the Western Zhou dynasty underwent enormous changes after 771 BC with the flight of the Zhou court to modern-day Luoyang and the diminution of its relevance and power. The Spring and Autumn period led to
9486-507: Was driven out of Qin. The remaining three allies, Qi, Wei and Han, attacked Qin, driving up the Yellow River below Shanxi to the Hangu Pass . After 3 years of fighting they took the pass and forced Qin to return territory to Han and Wei. They next inflicted major defeats on Yan and Chu. During the 5-year administration of Lord Mengchang, Qi was the major power in China. In 294, Lord Mengchang
9588-522: 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
9690-477: Was guided by his prime minister Zhang Yi , a prominent representative of the School of Diplomacy . He was followed in 323 BC by King Xuanhui of Han and King Yi of Yan , as well as King Cuo of the minor state Zhongshan. In 318 BC even the ruler of Song , a relatively minor state, declared himself king. Uniquely, while King Wuling of Zhao had joined the other kings in declaring himself king, he retracted this order in 318 BC, after Zhao suffered
9792-437: Was held by figurehead rulers of the Zhou dynasty, while the rulers of most states held the title of duke ( gong , 公 ) or marquess ( hou , 侯 ). A major exception was Chu, whose rulers were called kings since King Wu of Chu started using the title c. 703 BC . In 344 BC the rulers of Qi and Wei mutually recognized each other as kings: King Wei of Qi and King Hui of Wei , in effect declaring their independence from
9894-499: Was implicated in a coup d'état and fled to Wei. His alliance system collapsed. Qi and Qin made a truce and pursued their own interests. Qi moved south against the state of Song whilst the Qin General Bai Qi pushed back eastward against a Han/Wei alliance, gaining victory at the Battle of Yique . In 288, King Zhao of Qin and King Min of Qi took the title di ( 帝 'emperor'), of the west and east respectively. They swore
9996-463: 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
10098-489: 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
10200-599: 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
10302-404: Was short in Qin relative to the other states at the time, Shang enacted policies to increase its manpower. As Qin peasants were recruited into the military, he encouraged active immigration of peasants from other states into Qin as a replacement workforce; this policy simultaneously increased the manpower of Qin and weakened the manpower of Qin's rivals. Shang made laws forcing citizens to marry at
10404-458: Was under siege. The state of Qi intervened. The famous Qi strategist, Sun Bin the great-great-great-grandson of Sun Tzu , the author of the Art of War , proposed to attack the Wei capital while the Wei army was tied up besieging Zhao. The strategy was a success; the Wei army hastily moved south to protect its capital, was caught on the road and decisively defeated at the Battle of Guiling . The battle
