WebStructure. As with any spatial reference system, ECEF consists of an abstract coordinate system (in this case, a conventional three-dimensional right-handed system), and a geodetic datum that binds the coordinate system to actual locations on the Earth.

These methods, … See more In geodetic coordinates, Earth's surface is approximated by an ellipsoid, and locations near the surface are described in terms of geodetic latitude ($${\displaystyle \phi }$$), longitude ($${\displaystyle \lambda }$$), and ellipsoidal height ($${\displaystyle h}$$). See more The Earth's tectonic plates move relative to one another in different directions at speeds on the order of 50 to 100 mm (2.0 to 3.9 in) per year. Therefore, locations on different plates are in motion relative to one another. For example, the longitudinal difference between … See more Horizontal datum The horizontal datum is the model used to measure positions on Earth. A specific point can have substantially different coordinates, depending on the datum used to make the measurement. There are hundreds of local … See more The difference in co-ordinates between datums is commonly referred to as datum shift.
