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).

GNIS query gives the Park's location, in decimal degrees, as: 37.8483188 (north latitude), −119.5571434 (west longitude) To solve: Choose the Decimal degrees format table; Find the 45° column; 37.8483188 is (slightly) closer to 45° than to 30° Find the 50 km row; 70 km is closer to 50 km than to 100 km
Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum. Geographic positions may also be expressed indirectly, as a distance in linear referencing or as a bearing and range from a known landmark. In turn, positions can determine a meaningful location, such as a street address.
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.
Hence, any 15 degree quadrangle can be identified by two letters; the easting (longitude) is given first, followed by the northing (latitude). These two letters are the first two characters of a full GEOREF coordinate. Each 15-degree quadrangle is further divided into smaller quadrangles, measuring 1 degree of longitude by 1 degree of latitude.
Longitude: from West to East this map definition covers 26.5 degrees. At an image width of 200 pixels, that is 0.1325 degrees per pixel. At an image width of 1000 pixels, that is 0.0265 degrees per pixel. Latitude: from North to South this map definition covers 13.35 degrees. At an image height of 200 pixels, that is 0.0668 degrees per pixel.
Longitude: from West to East this map definition covers 70.4 degrees. At an image width of 200 pixels, that is 0.352 degrees per pixel. At an image width of 1000 pixels, that is 0.0704 degrees per pixel. Latitude: from North to South this map definition covers 39.3 degrees. At an image height of 200 pixels, that is 0.1965 degrees per pixel.
