The aim of the paper is to eliminate the redundant data included in a geographical information system (GIS) involving surface analysis. Because the GIS applications are used to solve problems from miscellaneous domains,is recommended that the spatial information and the particularities of the area involved to be combined in one raster layer. Principal component analysis applied to raster layers gives such a facility. The studied surface is about 2.5hectares and is a part of the campus of University of Agricultural Science and Veterinary Medicine from Cluj-Napoca. The digital elevation model for the studied area will be generated and the slope and aspect raster layers derived from DEM will be combined using the principal component analysis in order to eliminate the redundant values from the new raster but to keep the particularities of the surface.
