Geoinformation and cartographic monitoring support for assessing the state of natural and man-made complexes in the Sakhalin Oblast
The regional land monitoring is carried out for evaluating of land resources, determining changes and prognosis of natural and technogenic processes, and developing recommendations to reduce or prevent the negative effects. The study used methods such as mathematical and GIS mapping, spatial analysis, and thematic interpretation.The results of monitoring are present in a cartographic form, and thus must be based on the actual maping data. The cartographical support at the monitoring system on regional level is a very difficult and relevant problem. In this paper the technical possibilities of information reception stations from satellites TERRA, Landsat, NOAA and others in the Sakhalin region were analyzed. As result of research, the methodological basis of the system of atlas geoinformation mapping (SAGIM) of the Sakhalin region was developed, which focused on ensuring the monitoring of natural and technogenic processes in the region.
