PyTrx contains functionality for deriving velocities, surface areas, and line measurements from oblique time-lapse imagery.

This version contains 5 example drivers, which demonstrate specific applications of this toolbox in glaciology:

1. Deriving glacier surface velocities using the feature-tracking tools;
2. Deriving surface areas of supraglacial lakes using the automated area detection tools;
3. Deriving surface areas of meltwater plumes using the manual area detection tools;
4. Deriving terminus profiles of a glacier using the manual line detection tools;
5. Deriving xyz positions of points which denote the location of calving events that have been distinguished in the image plane.

These driver scripts can be adapted and modified to use in other applications.
