Geodesic methods for modeling and protection of megalopolis objects

Abstract

This article presents new techniques for the use of geodetic instruments when performing work on monitoring deformation processes and protecting monuments of cultural heritage. The prevention of dangerous deformations and destruction of building structures is an extremely important task, the solution of which ensures the preservation of all construction costs. For this reason, an increased attention was given to the development of early detection methods of possible structural damage to structural elements. There are many different methods for detecting displacement. Nevertheless, little work has been devoted to the development of real time observation methods. In addition to the existing methods, a permanently operating observation station is considered. The new method is based on: 1-The use of robotic motorized total station; 2- A preliminary calculation of the measurement accuracy. The actual results of the observations are given. Besides, the technique of preserving monuments of cultural heritage, including the creation of their models based on laser scanning and survey with unmanned aerial vehicles, is shown.
