Trimble Geodetic Library Installation Guide

What is Trimble Geodetic Library?

The Trimble Geodetic Library (TGL) is a set of software libraries commonly used across Trimble to transform geodetic coordinates (latitude, longitude, height) into plane coordinates and elevation (north, east, elevation), as well as to perform time-dependent datum transformations as and other geodetic computations.

How does TGL find the files it needs?

Install the coordinatesystemmanager-3.10.1.msi or Trimble Business Center. Quadri will check if the Geodata part is installed. Learn more about Coordinate System Manager.
