[Design and implementation of a landscape analysis system based on remote sensing data].
Because of the functions of Geographic Information System(GIS) being not satisfied to the requirements of landscape analysis, a landscape analysis system was designed with Visual C++ and demonstrated with remote sensing data. This system adopted the method f picking-up patch boundary pixel set, improved the patch searching speed, and supplied some landscape analysis functions, such as the calculation of the distance between patches, and the boundary length of neighboring patch, which are not provided by current GIS. It was used to analyzed the landscape of suburbs in northwest Beijing, and the shortcomings of current GIS applied in landscape analysis were overcome.
