Abstract

We are interested in the problem of modeling the propagation of landslides. We use an image processing approach based on the computation of a geodesic distance map. We determine the evolution of an initial curve along a given surface. The model can incorporate various properties coming from the geometry of the surface or independant measures. In an application, we focus on landslides study in the context of natural risk management The model is driven by geometrical constraints and SAR interferometric measures.
