GPS matavimų rezultatų ir kvazigeoido skaitmeninio modelio panaudojimas nustatant geodezinius aukščius
Abstract
On Lithuanian territory, the zero, first and second order GPS networks were developed. Also, the geoid (quasigeoid) digital model was determined by the Geoid Determination Working Group of the Nordic Countries Geodetic Commission for Lithuanian territory. It is neeesary to know the accuracy allowing to obtain the normal heights from such data.
