Provides access to members that control the 3D vector transformation with rotation, translation and scaling.
The Position Vector transformation converts data between geographic coordinate systems. It uses seven parameters including three translations, three rotations, and a scale factor.
The parameters include three translations, three rotations, and a scale factor.
The translations are in meters, the rotations are in arc seconds, and the scale factor is in parts per million.
The transformation is done in a XYZ system.

| Interfaces | Description |
|---|---|
| IGeoTransformation | Provides access to members that define a geographic (datum) transformation. |
| 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. |
| CoClasses and Classes | Description |
|---|---|
| PositionVectorTransformation | Creates a Position Vector transformation. |
The rotation values are defined as clockwise as you look towards the origin of the XYZ system.
The Coordinate Frame transformation defines the rotations in the opposite direction. If you change the signs of the rotations for either method, you can apply them to other method.
