Kakovost določitve nadmorskih višin z GNSS-višinomerstvom na območju Ljubljane (= Quality determination of mean sea level heights with GNSS levelling on the Ljubljana city area)

Abstract

This paper describes the quality determination of heights above mean sea level using RTK GNSS-levelling and new height reference surface SLO_VRP2016/Koper on the city area of Ljubljana. At 57 chosen benchmarks, quasigeoid heights were determined using ellipsoidal heights, determined with RTK GNNS-levelling technique and heights above mean sea level in the new height system SVS2010. The measured quasigeoid heights were compared with values interpolated from the new height reference surface SLO_VRP2016/Koper.
