The local origin is described by the … WebHowever, as the reference surface is a transposition from an ellipsoid to a plane, some deformations appear. The commonly used coordinates are E, N (East, North). It’s important to understand that a projection is associated to a geodetic reference system so two projections don't always have the same base. The NED frame (North East Down)

It consists of three coordinates: one represents the position along the northern axis, one along the local eastern axis, and one represents the vertical position. Two right-handed variants exist: east, north, up ( ENU) coordinates and north, east, down ( NED) coordinates.
