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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
