摘要:What are the benefits of moderate resolution data and which parameters could the user receive from these data. The following text tries to give some answers to this question.In an examination, the satellite images from the sensors MODIS (Moderate Resolution Imaging Spectroradiometer), ASTER (Advanced Space borne Thermal Emission and Reflection Radiometer) and LANDSAT are compared to show which parameters for vegetation models, e.g. the Leaf Area Index (LAI), the Normalized Differenced Vegetation Index (NDVI) or the Photo Synthetically Active Radiation (APAR) can be estimated. Therefore specific vegetation models were developed to estimate the "carbon reservoir". In the present thesis the adapted model is the Global Production Efficiency Model (GLOPEM) invented by Goetz et al. (1996).All parameters were compared with a classification of the standard Maximum Likelihood (ML) and Minimum Distance to mean (MD) methods. The accuracy of the ASTER data in comparison with CORINE Land Cover 2000 lies around 80 percent and declares the best results. But also the results of the MODIS and LANDSAT images were beneath the marks of ASTER
