Glacier Image Velocimetry (GIV) is a toolbox for calculating timeseries of glacier flow velocities from optical satellite imagery.
​
GIV is easy to use and allows you to rapidly calculate glacier flow over multiple years, over many glaciers and at high resolution - all though a convenient user interface and without needing to do any coding.
GIV aims to be versatile enough for use in research, and convenient enough for use in teaching (and undergraduate dissertations, etc). Have a look at our documentation below, including the full source code, a video tutorial, pdf user manual and 2021 paper in The Cryosphere.

Thanks for watching, and I hope the tutorial was helpful. Check the youtube video descriptions, our TC paper and GIV pdf user manual (download above) for additional details. And try it out - it has an easy learning curve and you will quickly produce some interesting results.
