Abstract

Currently, geospatial 3D modeling is one of the modern ways to represent digital geodetic data on the size and shape of the objects under study. However, the publication of requirements and recommendations in methodological and regulatory documents describing the use of laser scanning in engineering-geodesy, as well as methods for analyzing the accuracy of the obtained measurements, today, significantly lags behind the market demand. In this regard, we propose an experimental technique that allows conducting field work using a robotic electronic total station Trimble SX10 with a laser scanning function and identify measurement errors, followed by an analysis of the influence of external and internal factors of deterioration in the quality of the data obtained, for example, facade surveying and creating a united 3D model of the Assumption Cathedral, located in Omsk.
