To develop a digital elevation model for the Nivagalsky license area the researchers have used the following process chain: vectoring - typology development - triangulation - spatial analysis. The researchers applied Spatial Analyst module of ArcGIS for working with raster spatial models in the GRID format; topographic map at a scale of 1:100 000 as a material for the databases; and Easy Trace software package, operating in Microsoft Windows, for semi-automatic vectorization of interactive topographic map of the area. After vectorizing four sheets of the topographic map of the license area in Easy Trace we received the following coverage: - large rivers (polygon coverage); - horizontals and elevations (linear and point coverage); - vegetation (polygon coverage). The researchers have used vector coverage contours and elevations digitized from the topographic map as the initial data for the terrain model. DEM (digital elevation model) of the Nivagalsky license area developed as a result of these operations has 14.876 triangles. Based on the analysis of physiographic data (physical geography, topography, natural water) in GIS the researchers have developed digital thematic maps (a hypsometric map, exposure and slope steepness maps) of the Nivagalsky oil and gas field. Southern and south-eastern slope exposures dominate at the tested area. The steepness of the slopes plays a decisive role in the development of the relief, causing the emergence of different denudation and accumulation processes within the slope. A significant part of the site is occupied by slightly sloping areas from 0 to 3°. Digital thematic maps are an essential stage in the preparation of project documents for the industrial development of the field. These maps allow research to obtain comprehensive data on the natural resources during the environmental monitoring of the field, conduct their own research and support the integration of geographic data in different subjects. A series of thematic maps will help facilitate management decisions while monitoring the Nivagalsky oil field and ease the planning of various engineering and construction works. The resulting maps can be used to generate an electronic atlas of Khanty-Mansiysk Autonomous District - Yugra and for landscape zoning of the area.geographic information systemsoil and gas fielddigital mapsгеоинформационные системынефтегазовое месторождениецифровые карты[Геоэкология и природопользование.
