Paper Abstract

Results of unsupervised classification of composite two- layered image are presented. Image consists of first layer TNDVI data, calculated on the base of LANDSAT-TM4 image and second layer DEM raster, created on the base of digital vector map. Different attempts to layers co-registering were tested. Raster type TNDVI image nonlinear polynomial transformation to digital map projection; nonlinear transformation of coordinates of digital map point coverage to LANDSAT-TM4 image coordinate system and then DEM raster creating; creating raster DEM on the base of point elevation data and then nonlinear transformation of DEM to LANDSAT-TM4 image coordinate system. Unexpected essentially big difference in clusters shape and position during unsupervised classification is showed and analyzed.
