Abstract. Using remote sensing data is currently the most simple and universal method for modeling surfaces. The main difficulty is in the preparatory process. This stage includes: 1) downloading files from the Internet; 2) merging several matrixes into a single matrix of digital elevation model (DEM), pruning by study area. Another important problem is the problem of editing DEM. Virtually all existing solutions are reduced to the matrix transformation to the vector map, association with other vector layers (for example, a map of the river bed) and the construction of the new matrix. Software package described in this paper will allow to avoid unnecessary steps and reduce errors in digital terrain model. In the future, this information system will be part of the web-based geographic information system to support the visualization and analysis of hydrodynamic calculations using remote sensing data. Software package will be useful in solving problems of ecological and economic nature for any territory on the planet.
Key words: geoinformation technologies, remote sensing, web-technologies, SRTM, digital terrian model.
