ITransformationMethodRMSError Interface

Provides access to transformation method RMS error.

Product Availability

Available with ArcGIS Desktop.

When To Use

Use the members on this interface to return RMS error information for either a control point combination (link) or the entire transformation.

The transformation must first be defined via ITransformationMethod before using these members. You can QI this method from ITransformationMethod.

Members

Description
Method GetControlPointError Returns the errors involved in moving control point i from the 'from' to 'to' system. These error terms are valid after using DefineFromControlPoints to define the transformation.
Method GetRMSError RMS (Root Mean Square) error expressed relative to the 'from' and 'to' points defining the transformation. These error terms are valid after using DefineFromControlPoints to define the transformation.
