A new geoid for the entire territory of the Republic of Croatia has been computed using point gravity data, ERS-2 satellite altimetry data, GPS/Levelling data, digital terrain models as well as the global geopotential model EGM96. The calculation of geoid undulations is accomplished by the collocation technique in a well-known remove-restore procedure. Taking benefit of the new gravity and altimetry data resulted in a significantly more accurate geoid model for Croatian land and sea territory in comparison to prior solutions, and to the more recent European EGG97 geoid. The obtained geoid surface should be useful for different purposes, particularly in the precise height definition using modern GPS technology. The application of this surface in modelling efforts of Adriatic Sea bathymetry from satellite altimetry is also planned.
