Geodesic provision for cadastral works: development prospects

Abstract

Abstract The article analyzes the geodesic provision development when performing a cadastral survey. It has been established that improvement will be manifested in the use of modern geodetic technologies - three-dimensional laser scanning. The analysis of literary sources showed that there is a significant number of scientific works on the use of laser scanning for obtaining cadastral data and creating a three-dimensional cadaster. Methods for performing cadastral surveys, criteria for choosing a measuring instrument, methods for assessing the accuracy of coordinates, algorithms for processing the scan data, building models have been developed. However, the issues of further use of three-dimensional information for the cadastral documentation preparation are practically not covered, while the cadastral documentation is the basis for introducing the information into the real estate cadaster. The article presents the results of performing the ground-based laser scanning of a linear object. Additional information that can be introduced to the real estate cadaster in connection with the use of three-dimensional technology - height, technical condition of a linear object has been established. The sections of the technical plan and the changes made to them have been given. In addition, it was revealed that when using three-dimensional data in the preparation of technical plans, it would be inevitable to develop the software that can create boundary, technical plans based on three-dimensional data.
