Abstract

This second part of the paper about the creation and compilation of the Christchurch, New Zealand, dataset for the detection of earthquake damages in urban areas deals with the extraction of additional information from the 3D model that can aid in the detection of destructions. This includes the creation of a height image of the scene, shadow and layover masks and using a modified version of the SAR simulator CohRaS® to simulate masks of the expected location of specular reflections in the real TerraSAR-X scene after the earthquake. The algorithms used for the extraction of these data sets and some ideas for their application for the damage detection task are discussed and first preliminary results are shown.
