Extended selection for UTM coordinate transformation

When you import AutoCAD data (dxf, dwg), UTM coordinate transformation provides the Extended selection option.

You can select any NTv2 files and define the source system and destination system for coordinate transformation. Thus, you can use coordinate transformation for countries other than the ones that are available in the Standard selection (Germany, Austria, Switzerland).

Note: The Extended selection option should be used only by users with in-depth knowledge of geodesy or surveying.

Note: An NTv2 file (GSB) defines only the ellipsoid transformation based on latitude and longitude (Lat/Lon). To work with the standard coordinate systems, you must define zones and projection for the source system and the destination system. The ellipsoid parameters will be taken from the NTv2 file.
