SummaryTerra SAR-X data will be incorporated into the regional change mapping program for monitoring the forests of Central Africa, sponsored by the Central Africa Regional Program for the Environment (CARPE). Currently, data from the MODerate Resolution Imaging Spectroradiometer (MODIS) are being used to calibrate regional maps of Landsat data in order to map forest change. Adding Terra SAR-X data to the inputs will improve the overall approach to characterizing change in two ways. First, Terra SAR-X will overcome the obvious limitations in mapping persistently cloudy areas with multi-spectral passive sensors. This is an issue of particular importance in the western part of the Congo basin in Gabon and Cameroon. Second, 16 meter ScanSAR data will be tested for mapping selective logging activities not readily detected with Landsat data. Two repeat coverages of the basin will be sought, 2 years apart, to test the feasibility of using TERRA SAR-X data for regional change monitoring.
