Inherits from

GEOCALCPBW_NAMESPACE::GeoBase

Description

The Projection class represents a method of transformation between the Earth's curved surface and a flat representation of the Earth's surface. The various types of projections supported in GeoCalc are outlined in the ClassType enumeration.
