LARGE-SCALE TOPOGRAPHIC SURVEYING FOR CONSTRUCTION NEEDS USING MODERN TECHNOLOGIES

Abstract

The article considers the process of topographic and geodetic works with the use of modern technologies and artificial Earth satellites (AES) as progressive methods of qualitative performance of applied tasks on determination of coordinates of construction objects and land plots for construction. It is substantiated that satellite navigation systems are a symbiosis of space technologies, devices and ground equipment and provide a wide range of applications in geodesy and topography, as they provide millimetre accuracy, reduce measurement time and, consequently, reduce the cost of their implementation. It is noted that satellite geodesy methods are conditionally divided into geometric and dynamic. The characteristics of each of them are briefly described. It is proved that modern geodesy plays a crucial role in construction, providing accurate and efficient surveying and mapping, improving information modelling of buildings, monitoring and inspection, ensuring the stability of the foundation and soil, and thus creating better and more durable structures.
