SummaryThe SAR data acquired under this proposal is decomposed into Kennaugh elements before being geocoded and calibrated using available global as well as local high resolution LIDAR DEMs. Terrain effects thus are reduced. Remaining influences are potentially removed by combining the Kennaugh elements to orientation invariant parameters. The multi-temporal combination and final normalization concludes the SAR pre-processing step. The geocoded SAR data subsequently is overlaid with multispectral data. The combination of SAR and multispectral data provides an ideal basis for empirical studies on plant traits, differentiation of forest structure parameters, and the detection of storm damages seen by SAR and multispectral sensors.
