Abstract

Pri transformaciji koordinat pridobljenih z GNSS izmero v lokalni koordinatni sistem je potrebno tudi višine preračunati iz elipsoidnih v nadmorske za kar potrebujemo dobro določen model geoida. V nalogi sem preveril, kolikšno je odstopanja državnega modela geoida SLOG2000 (Pribičević, 2000) od dejanske vrednosti na območju Radovljice z interpolacijo ravnine, ki predstavlja potek geoida na izbranem območju. Ravnina je bila interpolirana preko točk na katerih se je izvajala statična GNSS izmera s katero smo določili elipsoidne višine in nivelman za pridobitev nadmorskih višin. Po analizi rezultatov je bilo razvidno, da državni model geoida na obravnavanem območju odstopa za povprečno 10 centimetrov.

Secondary title: Determination of the local geoid model in the area of Radovljica
Secondary abstract: At the transformation of the GNSS measured coordinates to the local coordinate system it’s necessary to convert heights from the ellipsoid system to heights above sea level (altitude), for what we need well defined geoid model. In this thesis I checked what is the derogation of national geoid model (SLOG2000) from the actual values on the area of Radovljica by interpolation of the local geoid undulation plane which represents actual values. Plane was interpolated over the points on which we conducted static GNSS survey for ellipsoid heights and leveling measurements for the above sea heights. Result analyze showed that average national geoid model derogation on the selected area is 10 centimeters.
