How to Create Glacier Velocity Maps with S1TBX

Adapted from the European Space Agency's STEP community platform


Why create a glacier velocity map?

Glacier velocity maps provide an intuitive and easily communicated method of showing glacier speed and direction. Offset tracking, used in this tutorial, is widely used in glacier motion estimation. This tutorial gives illustrated step-by-step instructions for creating Sentinel-1 glacier velocity maps.
