Sažetak
The EUVN points are represent one basic element of the European geodetic infrastructure. They serve as a control of the existing continental and national geoid solutions and for the estimation of height datum differences. After the first analysis, discrepancies between gravimetric geoid EGG97 and the point-wise EUVN geoid were detected due to errors in one of compared models. Croatian Geodetic Institute (CGI) received all materials related to EUVN project from the State Geodetic Administration. Analyse of the received materials shows that some height data, which have been sent to the EUREFUELN data centre, were calculated using benchmarks whose heights are in different height datum. This paper represents discrepancies between EGG97 and EUVN after using uniform new official height datum in Croatia – HVRS71 and densification project EUVN_DA on the territory of the Republic of Croatia.
