👉 The word 'WGS' (World Geodetic System) is a set of mathematical equations that are used to calculate coordinates, distances, angles and positions in various geographic coordinate systems, including the International Date Line, the Earth's surface, and celestial spheres. These equations are fundamental for mapping and navigation purposes. In general, a WGS system is an extension of the Mercator projection which uses a series of ellipses to represent the Earth. This makes it possible to use the system in multiple coordinate systems including longitude, latitude, bearing, altitude, elevation, etc. The WGS system is designed for mapping and navigation purposes but also has applications in civil engineering, transportation, surveying, robotics and other fields.
