GEODESY, CARTOGRAPHY AND AERIAL PHOTOGRAPHY

The aim of this work – research topological inconsistencies during adjustment and junction adjacent map sheets digital topographic maps scale 1:50000 with the use rigorous analytical geodetic methods on reference ellipsoid in geoinformation environment. analyzes phenomenon frames within zones Gauss-Krueger projections feasibility transition to environment creation database “The Main state map” by determining differences between vertices at a 1: 50000 boundaries projection zones. This was discovered enterprise “Research Institute Geodesy Cartography”. dependences are shown analyzed, which show changes distances longitude latitude. These values range from 1 mm 8 mm, leads form gaps overlaps sheets. complicate process make it impossible automate features into database. scientific novelty is justify tools instead analog cartometric standard instrumental GIS; ellipsoid, not just cartographic projections, spheroid or sphere. practical significance that significantly minimize overlaps, as establishment tolerances for these does correct performed can be used create Basic 10000”, updating geospatial data implementation determine characteristics using GIS. Given results research, we conclude present stage application geographic information systems activities requires increasing level topology accuracy all methods, extremely directly ellipsoid.
