e) Height differences going from the national height reference frame of Sweden (RH 2000) to zero-tide
EVRF2019 (mean -7 mm; min. -19 mm; max. -2 mm)
Keeping the aforementioned developments in mind, the common reference level Baltic Sea Chart
Datum 2000 (BSCD2000) has been specified with the aim to
=s> replace the existing variety of reference levels by a seamless chart datum definition for the
entire Baltic Sea;
=s> simplify the determination and use of bathymetric charts by using the existing European
geodetic standards (European Terrestrial Reference System 1989 and European Vertical
Reference System 2000) and to make the marine infrastructure of the Baltic Sea fully
interoperable with the national geodetic infrastructure, namely the national satellite-based
positioning services (e.g., SAPOS, SWEPOS, FinnRef) and the national height systems;
thereby
=s> provide an optimal support for current and future marine GNSS aided applications and
=s> comply with future S-10X standards of the International Hydrographic Organization (IHO).
