The purpose of the work was to indicate the potential use of Google Earth maps for selected geodetic works (preparing topographic descriptions, sketch maps) in order to facilitate and accelerate the process. Works were carried out in an urban area, Wolności Square in Poznań (Poland) where 58 checkpoints were located. In order to design them, maps from the Google system from four periods were used. The research used the Global Navigation Satellite Systems set consisting of a Leica GS08 + satellite receiver and a Leica CS15 controller, geodetic software for work design (Trimble GNSS Planning Online) and calculations (C-Geo 8) as well as cartographic materials and data obtained from the Municipal Center of Geodetic and Cartographic Documentation in Poznań: the master map, catalog data and topographic descriptions of the reference points. The results show that the accuracy of the location of points offered by Google is greater than declared by the system operators. However, it is not sufficient for applications in the assumed geodetic works.</p>}, number={A 71}, journal={Badania Fizjograficzne Seria A - Geografia Fizyczna}, author={KUBIAK, JAROSŁAW and MAGDA, PAULINA}, year={2020}, month={grudz.}, pages={65–74} }
