    Geodetic systems or geodetic data are used in geodesy, navigation, surveying by cartographers and satellite navigation systems to translate positions indicated on their products to their real position on earth. The systems are needed because the earth is an imperfect ellipsoid. A datum (plural datums) is a set of values used to define a specific geodetic system. The difference in co-ordinates between datums is commonly referred to as datum shift.
