DatumTransform Class

Inherits from

Description

The DatumTransform class represents a transformation that will convert coordinates given in one HorizontalDatum to coordinates in another. There are several types of datum transforms supported by GeoCalc, and they are outlined in the ClassType enumeration.

Constructors

Constructor	Description
DatumTransform	Creates a new instance of the DatumTransform class
