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 from spaceborne SAR data. It relies on correlation between damage level at an urban block level and some selected texture measures computed on post-event, Very-High-Resolution (VHR) spaceborne SAR reflectivity maps. Some experiments have then been conducted on ERS and ERS-like data offered by the European Space Agency and reprocessed to optimize spatial resolution, in order to test whether also these types of data, offering large repositories of pre-event items, may also be employed for this purpose. Preliminary results are presented in this paper.
