АВТОМАТИЧЕСКОЕ ВЫДЕЛЕНИЕ ФОРМ И КОМПЛЕКСОВ РЕЛЬЕФА НА ОСНОВЕ МОРФОМЕТРИЧЕСКОГО ГИС-АНАЛИЗА (НА ПРИМЕРЕ ВЕНГЕРОВСКОГО РАЙОНА НОВОСИБИРСКОЙ ОБЛАСТИ)

The author suggests an approach to automatic geomorphological zoning by relief types. The method is based on a combination of standard techniques of grid analysis (software package ArсGIS 9.3) and pattern recognition methods (supervised classification) widely used for processing multispectral satellite images (software package ENVI 4.5). The initial data are morphometric characteristics obtained from SRTM by means of moving average. There are two alternative ways of morpho-complexes schemes compiling. In the first case discrete landforms are derived by morphometric parameters, and morpho-complexes are then delineated by their areas ratio in a moving window. In another case, the morphometric parameters are loaded into the software ENVI 4.5 as channels, where supervised classification is performed. The sites which are definitely diagnosed by their historical and genetic aspects serve as a model area. The resulting morpho-complex schemes show a good agreement. The proposed approach is easy to learn. It also significantly reduces the complexity and routine work duration in geomorphologic mapping.
