Quantities which define the position of a point on the spheroid of reference (for example, the Earth) with respect to the planes of the geodetic equator and of a reference meridian. Commonly expressed in terms of latitude and longitude.
the latitude and longitude of a point on the Earth's surface determined from the geodetic vertical (normal to the specified spheroid). (See zenith; latitude, terrestrial; longitude, terrestrial.)
Latitude, longitude and altitude; for specifying positions. All are defined relative to the geode ("mean sea level"). Altitude and latitude have first-order dependence on the departure of the geode from a spherical shape; longitude has a second order dependence that is neglected in the ISO calculations. See definitions of each coordinate for details.
The quantities of geodetic latitude or longitude that define the position of a point on the surface of the earth with respect to the reference spheroid.
Angular coordinates (longitude and latitude) closely related to spherical polar coordinates and defined relative to a particular Earth geodetic datum. Also referred to as geographic coordinates.
A system of geographic position referencing. Angular measurements of latitude and longitude are projected onto a well-defined reference ellipsoid that approximates the earth`s irregular shape.
