HorizontalDatum Class

Inherits from

GEOCALCPBW_NAMESPACE::Datum

Description

The HorizontalDatum class provides a frame of reference for expressing locations within a coordinate system. A HorizontalDatum is defined by an Ellipsoid, which gives a mathematical approximation of the shape and size of the Earth, and by a PrimeMeridian, which provides an origin for expressing locations on the Ellipsoid.
