This study is dedicated to the development of efficient methods for modeling terrain, providing the solution of problems of different scales of ecological and geographical research. A system of quantitative morphometric analysis methods of relief was developed. Also it includes the methods of detection and analysis of DEM errors. The developed methods are applied to ecological and geographical research of test plots area. The study used GIS technology and mapping method. In this paper we tested the algorithm of landforms transformation due to changes in the slope area, then created a geodatabase of the territory of the test sites. The initial data were topographic maps and remote sensing products. The algorithm was implemented in geoinformation environment and we compose technique of mapping morphometric characteristics. Also was used the technique of predictive mapping changes landforms due to the local characteristics of slope provided spatially homogeneous precipitation, soil and vegetation conditions. The results are stored in a pre-designed geodatabase. In the work we created maps of watersheds, slopes and changes landforms, landuse of test areas. After that we analyzed the distribution characteristics within the watershed. Data analysis allowed us to determine violations within the water protection zone which established pursuant Federal law about guard of water resources of Russian Federation. In addition we determined the landuse in areas with slopes greater than 3 deg, and in the border of material demolition\ accumulation.
