О проектных работах при создании опорных геодезических сетей с использованием ГИС-технологий

Abstract

During the last decades Geodesy and other Earth Sciences have undergone revolutionary changes concerning the use of Global Positioning Systems. Currently, traditional geodetic and topographic technologies are giving way to high-precision, productive and all-weather space systems. In 1995 the Federal Service of Geodesy and Cartography approved “the Concept of transiting topographic and geodetic production to autonomous methods of satellite coordinate definitions”. The transition to new technologies entails restructuring not only the methods of determining the coordinates, but also the stages of pre-design and design work. Currently, there has been intensive penetration of geoinformation technologies into sciences related to the analysis and processing spatially coordinated data, and geodetic data in particular. Specialized software products are developed but they are quite expensive and difficult for mastering. The authors describe the opportunities of using standard geographic information systems (for example, GIS ArcView V. 3.1) in the view of their spatial orientation for the analysis and optimal selection of the points of the initial geodetic framework and effective implementation of the complex of geodetic works, in order to accurately determine the coordinates of the points of the created geodetic reference network.
