چکیده

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. * Corresponding author

Automated Dem Extraction of Urban Areas from Multi Resolution Satellite Images

This paper reports experiments carried out for automated extraction of a digital elevation model (DEM) from satellite images. In particular, this paper focuses on DEM extraction from dense urban areas where there are occlusions, shadow and height discontinuities. These properties have been known to create many problems in stereo matching and for automated DEM extraction. Using satellite images ...

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images

As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
