Detailed Description

DtMapDatums represent a spheroid model of the earth, with a data shift to facilitate easy conversion to geocentric systems.

DtMapDatums are used in conversions between geocentric and geodetic coordinates. There are many MAP datums available, the default is DtWGS84 which was created in 1984 for the whole world. Some MAP Datums are good for specific parts of the world. This class is designed to be subclassed and extended.

VR-Link provides implementations of many common Spheroid's used in simulations.
