Datum Transformation

Datum transformation is a process used in mapping and geodesy to convert geographic coordinates from one reference system (datum) to another. Since different datums may use varying models of the Earth's shape and location data, transformations ensure that coordinates align accurately across systems. This involves mathematical calculations or parameters that adjust positions, accounting for differences in how each datum represents the Earth's surface. Essentially, it converts geographic data so that maps and GPS devices referencing different datums can work together consistently, providing precise location information across various mapping and navigation platforms.
