Large surface displacements measured with feature tracking

5th GeoHazards Challenge (GH5)


Challenge Description

When the surface deformation due to seismic events, volcanic activity, glacier motion, and/or slope instability is too large (meters or tens of meters) radar interferometry cannot be used due to decorrelation of SAR signal. In this case, feature tracking techniques can be applied. These approaches are convenient because they can be applied in a very similar way to different data sources, as for example optical and radar imagery. The aim of this challenge is to implement ad-hoc feature tracking algorithms to be applied to Sentinel-1 (radar) and Sentinel-2 (multispectral) satellite imagery.





The results below are divided into Software Repositories, Data Processing Pipeline Services and Data Product Repositories.  In case you would like to get in touch about specific results, please use the indicated reference code.
