datum transformation
Définition
- A datum transformation is a mathematical calculation that converts location coordinates referenced to one datum to location coordinates referenced to another datum. This calculation does not involve an actual physical relocation of the point in question, but a redefinition of its position relative to a different set of coordinate axes and a different origin point.
