Geographic Transformations


Specify transformation methods that can be used to project data on the fly.

Often, when data is projected on the fly it requires a transformation method. You can create a list of transformation methods the application can choose from, such as custom transformations (those created using the Create Custom Geographic Transformation tool) and system supplied transformations (those out of the box).
