ArcObjects Library Reference (Geometry)  

IGeoTransformation Interface

Provides access to members that define a geographic (datum) transformation.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

Most methods and properties are inherited from ITransformation. Each geographic (datum) transformation also has a name, a 'from', and a 'to' spatial reference.

Members

Description
Method GetSpatialReferences Returns the from and to spatial references for the transformation.
Read/write property Name The name of the geographic transformation.
Method PutSpatialReferences Sets the from and to spatial references for the transformation.
Method TransformMeasuresFF Transforms floating point measures to floating point measures (or do the inverse).
Method TransformMeasuresFI Transforms floating point measures to integer measures (or do the inverse).
Method TransformMeasuresIF Transforms integer measures to floating point measures (or do the inverse).
Method TransformMeasuresII Transforms integer measures to integer measures (or do the inverse).
Method TransformPointsFF Transforms floating point points to floating point points (or do the inverse).
Method TransformPointsFI Transforms floating point points to integer points (or do the inverse).
Method TransformPointsIF Transforms integer points to floating point points (or do the inverse).
Method TransformPointsII Transforms integer points to integer points (or do the inverse).

Inherited Interfaces

Interfaces Description
ITransformation Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on.
