Abstract | The Baltic Sea Chart Datum 2000 (BSCD2000) is a geodetic reference system adopted for the Baltic Sea water level information and effective use of GNSS methods for accurate navigation and real-time offshore surveying (Schwabe et al. 2020). The BSCD2000 will be realized through GNSS and quasigeoid modeling and is compatible with the European Vertical Reference System (EVRS) associated national height system realizations of the Baltic Sea countries. Since BSCD2000 will be realized through quasigeoid modeling, it is essential to validate the modeling results using, for instance, GNSS-leveling control points. This data publication consists of the Estonian high precision GNSS-leveling control points used to validate the BSCD2000 solutions but can be employed similarly to validate any other quasigeoid model. The data made available is specified in three versions:
Note that the GNSS ellipsoidal heights are given relative to the GRS80 reference ellipsoid. The description of the data columns is provided in the README file.
