摘要：The usefulness and acceptance of geoinformation systems (GIS) mainly depend on the quality of the underlying geodata. The aim of this paper is to introduce an approach for the verification of cropland and grassland objects in a GIS. The approach compares the GIS objects with data derived from high resolution remote sensing imagery using image analysis techniques. Textural, structural, and radiometric features are assessed in order to check whether a cropland or grassland object in the GIS is correct or not. The approach is presented in detail, and examples are given for various stages of the method. Both the potential and the limitations of the system are also discussed
