Trimble Geodetic Library Installation

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.

Installing TGL locally

TGL acts as a local coordinate system fallback when working with Single User Models. Installing it locally allows you to create and manage coordinate systems without an active internet connection.

How does TGL find the files it needs?
