APPLICATION OF LASER SCANNING TECHNOLOGY FOR DIGITAL MODELING OF OBJECTS ON THE EARTH'S SURFACE

Abstract

This article explores the use of three-dimensional laser scanning for acquiring digital data of surface objects. In recent years, this technology has been increasingly applied in Uzbekistan due to its high precision, speed, and user-friendliness. The paper covers both terrestrial and aerial survey methods, highlighting their role in the creation of digital maps and topographic plans. The operational principles of laser scanners are described in detail, including distance calculation, coordinate registration, and real-time 3D model generation. Special attention is given to the application of laser scanning in civil construction, engineering geodesy, and cadastral projects. The study emphasizes that laser scanning enables millimeter-level measurement accuracy without the need for reflectors or additional equipment, while significantly automating labor-intensive geodetic tasks. The use of laser scanning is positioned as a key element in improving the quality of engineering projects and in enabling efficient spatial data management.
