Detailed Description

Implements valid Datum options and related parameters which account for different earth spheroids.

Specifies planimetric TeDatum parameters to be used for defining geodetic coordinates, which are necessary to establish a map projection system. It encapsulates the following important information regarding a planimetric Datum such as:

• Datum name;
• Earth equatorial radius;
• Earth flatenning;
• Datum shifts.
