1. geoid

   A geocode is a code that represents a geographic entity (location or object). It is a unique identifier of the entity, to distinguish it from others in a finite set of geographic entities. In general the geocode is a human-readable and short identifier.

1. Geoid

   The geoid, simply stated, is the shape that the surface of the oceans would take under the influence of gravity alone. All points on that surface have the same scalar potential—there is no difference in potential energy between any two. In that idealized situation, other influences such as winds due to solar heating and tides have no effect. The surface of the geoid is farther away from the center of the Earth where the gravity is weaker, and nearer where it is stronger. The differences in gravity, and hence the scalar potential field, arise from the uneven distribution of the density of matter in the earth. Specifically, the geoid is the equipotential surface that would coincide with the mean ocean surface of the Earth if the oceans and atmosphere were in equilibrium, at rest relative to the rotating Earth, and extended through the continents. According to Gauss, who first described it, it is the "mathematical figure of the Earth", a smooth but highly irregular surface that corresponds not to the actual surface of the Earth's crust, but to a surface which can only be known through extensive gravitational measurements and calculations. Despite being an important concept for almost two hundred years in the history of geodesy and geophysics, it has only been defined to high precision in recent decades, for instance by works of Petr Vaníček, and others. It is often described as the true physical figure of the Earth, in contrast to the idealized geometrical figure of a reference ellipsoid.
