The Assessment of Environmental Situation in the YaNAO Using Satellite Imagery in GIS-technology

Abstract

The article addressed the issues of integrated environmental assessment based on the results of chemical analysis and satellite monitoring data. The method for estimating the anthropogenic load and the degree of territories degradation in the areas of oil production using the normalized difference vegetation index (NDVI), characterizing the change in the state of the vegetation cover, has been proposed. The dynamic of vegetation state change in the Yamal-Nenets Autonomous Okrug was calculated using Landsat satellite imagery data on the basis of GIS ArcGIS Desktop and the results were compared with the data of field observations of the environmental situation. A stable correlation between the NDVI change and the increase of pollution level of the territory was revealed. The thematic maps in GIS were created according to results of analysis.
