Abstract

As part of the GMES Service Element project Forest Monitoring, a service that utilizes space-borne synthetic aperture radar (SAR) data supported by a sample of optical satellite was established. Three SAR ortho-rectified mosaics using C band radar data from 1992/1993, 2003/2004, and 2006/2007 were compiled. Three features, average amplitude, temporal variability and average texture, were computed using overlapping radar imagery. Land cover / Land cover change map was produced and the result was compared with a sample point set that was selected from optical satellite data by the IFN. The overall accuracy was 95.6 % but per-point accuracy of change detection was poor.
