Abstract

By using data analysis using full-polarimetric measurement results, we can estimate area-averaged urban parameters which can not be observed from simple HH, HV and VV pseudo-color map due to insufficiency of spatial resolution of POLSAR. For example, estimation of urban buildings density or building orientation is reported. In the above estimation, we analyzed air-borne Pi-SAR and satellite-borne PALSAR data as POLSAR observations measured over Tokyo area. For evaluation of the estimated results, we adopt high-resolution optical observation data from QuickBird and 1/2500 POLYGON map surveyed by Tokyo Metropolitan Office.
