GeodeticDatumProps Interface
This interface represents a geodetic datum. Geodetic datums are based on an ellipsoid. In addition to the ellipsoid definition they are the base for longitude/latitude coordinates. Geodetic datums are the basis for geodetic transformations. Most geodetic datums are defined by specifying the transformation to the common base WGS84 (or local equivalent). The transforms property can contain the definition of the transformation path to WGS84. Sometimes there exists transformation paths direct from one non-WGS84 datum to another non-WGS84. The current model does not allow specifications of these special paths at the moment.
