PERFORMING ENGINEERING AND GEODETIC SURVEYS TO BUILD A THREE-DIMENSIONAL INFORMATION MODEL USING THE EXAMPLE OF THE EAST SIBERIAN TRAINING CENTER POLYGON

Abstract

Today, thanks to rapidly developing digital technologies, it has become possible to create an exact copy of a real object in a three-dimensional information space. Such a copy can digitally reflect the physical, functional and other characteristics of the object. Based on the above, this technology is promising in various technical fields, especially in the design of various facilities. This article presents the technological process of creating a topographic base in order to form a three-dimensional information model of a training railway training ground. The execution of geodetic surveys begins with an inspection of the area and the breakdown of the points of the planned high-altitude justification. The terrain is surveyed from the points of planned high-altitude justification with high-precision modern geodetic instruments (total station, optical level) and using a global navigation satellite system with sufficient characteristics for these surveys. The measurements obtained will be required to create a topographic plan of the area on a scale of 1:500. The processing of the received data was carried out using specialized software. Based on the results obtained, a digital terrain model is built, which displays the entire situation of the terrain of the training railway training ground. The model is built based on the instructions for topographic survey using a given scale. Based on the obtained topographic basis of the area, a three-dimensional information model will be built, which will be used both in educational activities and for construction work on the modernization of the training ground.
