SRTM

This article is devoted to questions of digital modeling of river basin area. The basin of the Tereshka River appears as the research object. The author results detailed algorithm of river basin geomodeling by using of computer software (ArcGIS, ESRI) on the basis of the space data (SRTM). Characterizing relief and water flow models are created. As a result watersheds and stream network are delineated.

This article considers the methodology for constructing a digital elevation model and its derivatives for analyzing the spatial distribution of linear erosion processes using the territory of the Khvalynsky district as an example. The authors propose the creation of a refined terrain model based on SRTM radar data, topographic maps and the interpretation of Earth remote sensing data. The creation technology is described and a comparative analysis of the refined model with the base SRTM is carried out.
