The study of seabed relief is part of operations by development of the mineral deposits, which are in the territory of water objects. All of them are required at the stage of industrial planning, construction and exploration, definition of geo-hazard, for the monitoring activity and also required to repel potential threats, including natural ones, etc. The uniqueness of the ecosystem and bioresources of the Caspian Sea against the backdrop of unfolding offshore oil production, sharply raises the issue of monitoring and forecasting water level fluctuations. Annual bathymetric studies in the territory of the sites allow the analysis of changes in the shape of the seabed relief.The digital model of relief, which is used in geology, geomorphology, cartography and many other application-oriented directions, is result of such operations. Article questions of creation DEM of a bottom, types and methods of obtaining bathymetric data are considered. Under the digital model of the topography (DEM) of the bottom is understood the organized structure of files containing vector representations of spatial objects of different types, attributive information about them and topological relationships between them. The comparative analysis of creation of DEM with different cell sizes and interpolation types of a digital grids is presented. Recommendations are given on the choice of DEM depending on the targeted use of the resulting data.
