THE HEIGHT SURVEY OF MOUNT ŁYSICA IN THE CONTEXT OF VERIFICATION OF GEODESICAL AND CARTOGRAPHIC STUDIES
Journal Title: Structure and Environment - Year 2019, Vol 11, Issue 2
Abstract
The subject of the article is the measurements of normal height (H) of the western top of Mount Łysica (Świętokrzyskie Mountains, Poland), carried out using the GNSS and geometric leveling methods according to standards for geodetic control network. As the elevation system EN-KRON86-NH was assumed. The reference data was the result of earlier measurements made using different methods: ALS, GNSS RTN and geometric levelling between selected points of Mount Łysica. The analysis of the survey results showed differences between the DEM from ALS measurement and the actual height reaching up to 0.47 m on small boulders and not exceeding the value of 0.17 m in the flat area. Differences between GNSS RTN measurement and geometric leveling based on GNSS static easurement did not exceed 0.03 m. An inventory of former state geodetic control network point “12 Góra Łysica” was also conducted. The point was found to be partially destroyed, and located 12 m south and 1.5 m below the actual top of the mountain. Therefore it was assumed, that a new geodetic control network point
