Transform known points command transforms coordinate values of points in a text file. This can be used, for example, to transform known ground control points from one projection system into another.
To transform a known points file:
1. Select Transform known points command from the Tools pulldown menu.
This opens the Source point file dialog, a standard dialog for selecting a file.
2. Select the file that stores the known points’ coordinates and click Open.

3. Define transformation settings and click OK.
This opens the Save transformed points dialog, a standard dialog for saving a file.
