THE CREATION OF GRAVITY FIELD ZONE MAP FOR THE TERRITORY OF THE RUSSIAN FEDERATION TO SELECT ISOLINE INTERVALS
The method of creation of gravity field zone map for the territory of the Russian federation is presented in the article. The map is designed to select isoline intervals depending on the nature of gravity field. The stages of zoning for regions selected, results consolidation and creation of a final zoning map are described. Recommendations for selecting isoline intervals for identified areas of field are suggested in the article. The algorithm for formalizing the selection isoline intervals for medium- and small-scale gravity field maps, based on spherical trapezoids discretization of created zoning map and spatial analysis of gravity field regions within grid cells, is considered in the article.
