This tutorial will highlight the capabilities of multimodal satellite imagery in addressing some of nowadays most impacting societal challenges using open source tools from CNES (French space agency).

This workshop will present a series of 3D open source tools from CNES (French space agency). We will start with two stereo satellite acquisitions and aim to produce a 3D change map. Our study case will be a part of the area affected by the 2020 Alex storm.
