153-456: A datum transformation such as a Helmert transformation , although in certain situations a simple translation may be sufficient. Datums may be global, meaning that they represent the whole Earth, or they may be local, meaning that they represent an ellipsoid best-fit to only a portion of the Earth. Examples of global datums include World Geodetic System (WGS 84, also known as EPSG:4326 ),
204-645: A choice of geodetic datum (including an Earth ellipsoid ), as different datums will yield different latitude and longitude values for the same location. The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene , who composed his now-lost Geography at the Library of Alexandria in the 3rd century BC. A century later, Hipparchus of Nicaea improved on this system by determining latitude from stellar measurements rather than solar altitude and determining longitude by timings of lunar eclipses , rather than dead reckoning . In
255-588: A point on Earth's surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses (often called great circles ), which converge at the North and South Poles. The meridian of the British Royal Observatory in Greenwich , in southeast London, England, is the international prime meridian , although some organizations—such as
306-473: A region of the surface of the Earth. Some newer datums are bound to the center of mass of the Earth. This combination of mathematical model and physical binding mean that anyone using the same datum will obtain the same location measurement for the same physical location. However, two different datums will usually yield different location measurements for the same physical location, which may appear to differ by as much as several hundred meters; this not because
357-411: Is 6,367,449 m . Since the Earth is an oblate spheroid , not spherical, that result can be off by several tenths of a percent; a better approximation of a longitudinal degree at latitude ϕ {\displaystyle \phi } is where Earth's equatorial radius a {\displaystyle a} equals 6,378,137 m and tan β = b

714-686: Is the exact distance along a parallel of latitude; getting the distance along the shortest route will be more work, but those two distances are always within 0.6 m of each other if the two points are one degree of longitude apart. Like any series of multiple-digit numbers, latitude-longitude pairs can be challenging to communicate and remember. Therefore, alternative schemes have been developed for encoding GCS coordinates into alphanumeric strings or words: These are not distinct coordinate systems, only alternative methods for expressing latitude and longitude measurements.

765-465: Is used to precisely measure latitude and longitude, while a vertical datum is used to measure elevation or altitude. Both types of datum bind a mathematical model of the shape of the earth (usually a reference ellipsoid for a horizontal datum, and a more precise geoid for a vertical datum) to the earth. Traditionally, this binding was created by a network of control points , surveyed locations at which monuments are installed, and were only accurate for

Ptolemy credited him with
1020-618: The 2014 off-season the USPHL lost the New York Applecore (Empire), but added the Providence Capitals (Elite & 16U), Jersey Shore Whalers (Empire), and the Richmond Generals (Elite, Empire) organizations to increase the total number of organizations to 35 headed into the 2014–15 season. During the 2014–15 season, the USPHL announce the creation of a Midwest Division to begin in the 2015–16 season by adding several teams from
1071-788: The 2015–16 continued into April when the New York Aviators announced their decision to leave the USPHL and join the North American 3 Eastern Hockey League (NA3EHL). The USPHL promptly reassigned the Aviator franchise to Rye, New York , and was renamed to the New York Dragons. In early April 2015, the Empire Division would expand to Daytona, Florida with the Daytona Racers. Also in April, it

In 2020, the USPHL Premier added the Anaheim Avalanche, Fresno Monsters , Las Vegas Thunderbirds , Northern Colorado Eagles, Ogden Mustangs , Pueblo Bulls , San Diego Sabers , Southern Oregon Spartans , and the Utah Outliers from the Western States Hockey League , another independent junior hockey organization. Complimentary additions to the USPHL Premier included Elmira Jr. Enforcers (renamed in 2023 to
1173-554: The 2024–25 season, the league plans to expand into Canada’s Quebec / Ontario provinces, effectively creating an entire new division. During the 2012–13 season, several organizations within the Eastern Junior Hockey League (EJHL) decided to form their own league and created the United States Premier Hockey League (USPHL). Those organizations also added their youth programs under the USPHL name as

This daily movement can be as much as a meter. Continental movement can be up to 10 cm a year, or 10 m in a century. A weather system high-pressure area can cause a sinking of 5 mm . Scandinavia is rising by 1 cm a year as a result of
1275-659: The Eastern Hockey Federation (EHF) youth leagues. The EHF organization already had many of the USPHL's junior organization's youth clubs. The league also rebranded its 16U Futures as 15U. On March 8, 2019, the USPHL and EHF announced plans to integrate the USPHL's High Performance Youth Division into the EHF to create the EHF South Division, expanding the youth league's footprint into the Mid-Atlantic region, beginning with
1326-646: The Elite Division the only Tier III feeder division. The Jersey Shore Whalers and the Florida Jr. Blades, both members of the former USP3 Division, were granted teams in the Premier Division, as well as the Jr. Blades adding their USP3 team to the Elite Division. The Skipjacks Hockey Club also added a Premier team to augment their teams in the youth divisions. The Wisconsin Muskies also announced they would field an expansion team in

At the time, the only USA Hockey-sanctioned Tier II league is the North American Hockey League . However, in December 2016, USA Hockey denied their application for a Tier II league. The USPHL launched its tuition-free league as the National Collegiate Development Conference . In response,
1683-436: The USPHL added a higher level junior league named the National Collegiate Development Conference (NCDC) for the 2017–18 season. The NCDC was seeking free-to-play Tier II junior league sanctioning, but was denied by USA Hockey. In response, the USPHL junior level leagues withdrew from USA Hockey sanctioning altogether. The 18U, 16U and 15U divisions are still considered Tier I youth hockey divisions by USA Hockey. Beginning in
1734-471: The USPHL also led the remaining EJHL teams to join the Atlantic Junior Hockey League and create the Eastern Hockey League (EHL). For the league's second season in 2014–15, the USPHL added the 16U Futures (16UF) Division for players who aspire to play midget hockey, but are not yet ready for the 16U Division. Eight organizations fielded teams in the 16UF Division for its first season. During
1785-615: The USPHL announced that the Elite and USP3 Divisions were expanding by splitting the teams from the one-year-old Midwest Division into the Elite and USP3 platforms. More changes came on May 20, 2016, when the USPHL added the four remaining teams from the former Northern Pacific Hockey League to the USP3 as a Pacific Division. Before the start of the season, the loss of the Illiana Blackbirds (Elite), Michigan Wild (USP3), and Marquette Royales (USP3)
1836-561: The USPHL dropped USA Hockey sanctioning from their junior level leagues and operates unsanctioned beginning with the 2017–18 season. In December 2016, the USPHL also announced the addition of six organizations from the Eastern Hockey League for the 2017–18 season: the previously mentioned Bandits, Rockets, and Cyclones would be joined by the Connecticut Nighthawks, Hartford Jr. Wolfpack , and New Hampshire Junior Monarchs . The New Hampshire Monarchs previously fielded USPHL teams in
1887-566: The center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels , as they are parallel to the Equator and to each other. The North Pole is 90° N; the South Pole is 90° S. The 0° parallel of latitude is designated the Equator , the fundamental plane of all geographic coordinate systems. The Equator divides the globe into Northern and Southern Hemispheres . The longitude λ of

1989-490: The distance they give is correct within a centimeter.) The formulae both return units of meters per degree. An alternative method to estimate the length of a longitudinal degree at latitude ϕ {\displaystyle \phi } is to assume a spherical Earth (to get the width per minute and second, divide by 60 and 3600, respectively): where Earth's average meridional radius M r {\displaystyle \textstyle {M_{r}}\,\!}
2040-468: The full adoption of longitude and latitude, rather than measuring latitude in terms of the length of the midsummer day. Ptolemy's 2nd-century Geography used the same prime meridian but measured latitude from the Equator instead. After their work was translated into Arabic in the 9th century, Al-Khwārizmī 's Book of the Description of the Earth corrected Marinus' and Ptolemy's errors regarding
2091-544: The league announced the formation of a High Performance Youth Division for the upcoming 2016–17 season. The new division added 14 and under (Bantams), 12 and under (Peewees), along with 10 and under (Squirts) to the USPHL umbrella. Charter members of the High Performance Youth Division were to include the New Jersey Rockets, Hartford Junior Wolfpack, Jersey Hitmen, and P.A.L. Jr. Islanders. In late April,

Mathematical cartography resumed in Europe following Maximus Planudes ' recovery of Ptolemy's text a little before 1300; the text was translated into Latin at Florence by Jacopo d'Angelo around 1407. In 1884, the United States hosted the International Meridian Conference , attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt
2193-461: The location has moved, but because the reference system used to measure it has shifted. Because any spatial reference system or map projection is ultimately calculated from latitude and longitude, it is crucial that they clearly state the datum on which they are based. For example, a UTM coordinate based on WGS84 will be different than a UTM coordinate based on NAD27 for the same location. Converting coordinates from one datum to another requires
2244-579: The longitude of the Royal Observatory in Greenwich , England as the zero-reference line. The Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911. The latitude ϕ of a point on Earth's surface is the angle between the equatorial plane and the straight line that passes through that point and through (or close to)
2295-460: The melting of the ice sheets of the last ice age , but neighboring Scotland is rising by only 0.2 cm . These changes are insignificant if a local datum is used, but are statistically significant if a global datum is used. On the GRS 80 or WGS 84 spheroid at sea level at the Equator, one latitudinal second measures 30.715 m , one latitudinal minute is 1843 m and one latitudinal degree
2346-539: The new Midwest Division saw a number of teams cease operations prior to the 2015–16 season including the Indiana Attack, Ironwood Fighting Yoopers, Minnesota Owls , Soo Firehawks, and St. Louis Storm due to lack of players. The Midwest Division did not have its own championship playoffs, but instead the top two teams in each conference from the Midwest and USP3 Divisions played for a single championship.
