Urban seismic damage assessment from post-event only SAR: preliminary tests on Envisat ASAR data

摘要

Some of the authors have recently proposed a new possible starting point for seismic damage assessment fromrnspaceborne SAR data. It relies on correlation between damage level at an urban block level and some selectedrntexture measures computed on post-event, Very-High-Resolution (VHR) spaceborne SAR reflectivity maps.rnSome experiments have then been conducted on ERS and ERS-like data offered by the European Space Agencyrnand reprocessed to optimize spatial resolution, in order to test whether also these types of data, offering large repositoriesrnof pre-event items, may also be employed for this purpose. Preliminary results are presented in thisrnpaper.
