Ishutina A. Evaluation of the geodetic network reliability at geomonitoring of built-up territories

The object of study - reliability points of geodetic networks. The purpose of research is to solve scientific and applied tasks of improving the reliability of geodetic monitoring by selecting reliable geodetic points on the results of their evaluation. Research methods is the theory of measurement errors, full-scale instrumental observation of vertical deformations of buildings and structures located on technogenic congested areas of the city of Dnepropetrovsk, digital modeling using GIS technology, comparative analysis of results of field studies on data reliability and application of the theory of random processes. A method for assessing the reliability of geodetic networks with the selection of stable geodetic points for interval estimates of errors determine their coordinates on the basis of the theory of probability and random processes. The first time the criteria for the allocation of plots in the urban area category of technogenic congested scoring based on the total impact of periodic and permanent technological factors as well, made zoning of the city on the degree of anthropogenic impact on the Earth's surface. The technique of geodetic monitoring of engineering facilities on the basis of determining the reliability of geodetic control points with reasonable frequency control them coordinate the application of satellite technology. Received further set of deformation depending buildings located in the zone of influence of underground construction, from the intensity of underground construction and remoteness from sources of anthropogenic impact on the living conditions c. Dnepropetrovsk. Completed studies allowed to develop measures to increase the reliability of engineering facilities heomonitorynhu cities located in different technogenic congested areas based on reliability estimation geodetic control points.
