Scientific paper

In this paper, we made a preliminary experimental evaluation of the capability to detect the urban changes due to an earthquake by InSAR and optical satellite based data. The test site is the area hit by the August 17th, 1999, Turkey earthquake. A multichannel/multitemporal dataset has been created including the intensity image of the pre event and the post event ERS acquisitions, the complex coherence and the intensity correlation coefficients. Using this SAR data set and the change detection provided by IRS, we performed a number of statistical tests to understand at what extent the InSAR is able to help detecting urban damages and what particular features extracted by SAR better contribute to this objective.
