2. Geodetic coordinates - Wikipedia

   en.wikipedia.org/wiki/Geodetic_coordinates

   Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).

3. Parallel 36°30′ north - Wikipedia

   en.wikipedia.org/wiki/Parallel_36°30′_north

   The parallel 36°30′ north is a circle of latitude that is 36 1 ⁄ 2 degrees north of the equator of the Earth. This parallel of latitude is particularly significant in the history of the United States as the line of the Missouri Compromise , which was used to divide the prospective slave and free states west of the Mississippi River , with ...

4. Geographic coordinate system - Wikipedia

   en.wikipedia.org/wiki/Geographic_coordinate_system

   A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.

5. 36th parallel north - Wikipedia

   en.wikipedia.org/wiki/36th_parallel_north

   The 36th parallel north is a circle of latitude that is 36 degrees north of the Earth's equatorial plane. It crosses Africa, the Mediterranean Sea, Asia, the Pacific Ocean, North America and the Atlantic Ocean. In the ancient Mediterranean world, its role for navigation and geography was similar to that played by the Equator today. [1]

6. World Geographic Reference System - Wikipedia

   en.wikipedia.org/wiki/World_geographic_reference...

   The first level of GEOREF divides the world into quadrangles each measuring 15 degrees of longitude by 15 degrees of latitude; this results in 24 zones of longitude and 12 bands of latitude. A longitude zone is identified by a letter from A to Z (omitting I and O) starting at 180 degrees and progressing eastward through the full 360 degrees of ...

   A GPS unit at confluence 53N 0, in Lincolnshire, England. The Degree Confluence Project is a World Wide Web-based all-volunteer project that aims to have people visit each of the integer degree intersections of latitude and longitude on Earth, posting photographs and a narrative of each visit online.

9. Latitude - Wikipedia

   en.wikipedia.org/wiki/Latitude

   The Equator has a latitude of 0°, the North Pole has a latitude of 90° North (written 90° N or +90°), and the South Pole has a latitude of 90° South (written 90° S or −90°). The latitude of an arbitrary point is the angle between the equatorial plane and the normal to the surface at that point: the normal to the surface of the sphere ...
