Since 2011 CNES, within the TOSCA project, has been funding the development of methodologies to quantify horizontal ground displacements caused by earthquakes, landslides, ice flows, dune migrations etc. All developments are integrated in the freeware, open-source photogrammetric software tool MicMac .
