Coordinate System Manager

Trimble Coordinate System Manager, bundled with Quadri for Windows, offers convenient access for viewing and editing Trimble's coordinate system database. While the default database often suffices with predefined coordinate systems, datums, ellipsoids, and geoid models, some users may require customization by editing existing entities or creating new ones to cater to their project-specific requirements.

For this kind of CRS tailoring, you will find a complete set of help topics in the Coordinate Systems Manager software. 

Install the software: coordinatesystemmanager-3.10.1.msi
