Digital mapping of territories using SLAM technology: analysis of the accuracy of the results obtained

The article addresses the issues of digital mapping of territories using modern equipment and innovative methods for performing topographic and geodetic work. Objective: To study modern territorial mapping methods and justify mapping approaches using SLAM technology. Methods and Results: The study employed a territorial mapping method using handheld laser scanners with SLAM technology. Terrain reconnaissance was conducted, control geodetic points were established, and fieldwork was performed using a Stonex X120GO scanner. The acquired point clouds were compared with the tacheometric survey results. Analysis of mean square errors confirmed that the accuracy met regulatory requirements. Scientific Novelty and Practical Significance: This study enables the evaluation of SLAM technology in ground-based handheld laser scanners as an alternative to traditional topographic surveying methods. When used correctly, this type of equipment fully meets the accuracy requirements for topographic plans at a scale of 1:500 and, in some cases, even 1:200. This, in turn, creates opportunities for the broader implementation of SLAM in topographic and geodetic practices. Applying SLAM technology and modern handheld laser scanners for topographic, geodetic, and mapping tasks can significantly reduce costs, resource consumption, and labor efforts while requiring fewer personnel and pieces of equipment. The study evaluates the possibilities of using SLAM technology and its accuracy. The article proves that using SLAM technology and handheld 3D scanners is an accurate and reliable tool for performing work in modern realities.
