3D-GIS for support of works on geotechnical monitoring of objects of main pipelines

Abstract

The article presents the results of the development of specialized 3D-GIS as a tool for structuring, storing, reproducing, processing and analyzing data for geotechnical monitoring of main pipeline facilities. The authors proposed a solution to the problem of the complexity of processing large amounts of data by creating a unified environment of geographically distributed information through a geo-portal and implementing services on the basis of the geo-portal for automated processing and analysis of information, as well as computational algorithms. The description of the structure and functionality of the developed 3D-GIS is given. Methods for obtaining and processing 3D data are disclosed, and the data is analyzed. Results of a quantitative assessment of changes in the natural environment, plan-elevation position and geometry of objects based on the data of several cycles of surveys by methods of ground and air laser scanning are presented. The advantages of 3D-GIS in solving problems of geotechnical monitoring, as well as the possibility of using 3D-models for solving other production and research problems are highlighted.
