Joachim Schwabe is a scientific staff member of the unit “Integrated Spatial Referencing” at
the German Federal Agency for Cartography and Geodesy (BKG). He graduated as a geodesist
from the Technische Universität Dresden (TUD) in 2008 and finalized his PhD thesis on regional
geoid modeling in the polar regions in 2015. An opportunity to assist the computations for the quasigeoid
model GCG2016 led him to the BKG, where he is now contact person for the GCG models
and GNSS-based height determination.

Jonas Ågren is associate professor in geodesy and senior lecturer at the University of Gävle in
Sweden. He is also part time senior geodesist at Lantmäteriet, the Swedish mapping, cadastral
and land registration authority. He received his PhD degree in physical geodesy at the Royal Institute
of Technology in Stockholm (KTH) in 2004. Since then he has worked with geoid modelling,
height systems and gravimetry in Sweden and the Nordic/Baltic countries. He was the chairman
of the working group on geoid and height systems of the Nordic Geodetic Commission (NKG) between
2010 and 2018, and leader of FAMOS activity 2 (Harmonising vertical datum/Improving
vessel navigation for the future) between 2015 and 2018.

Gunter Liebsch is head of the unit “Integrated Spatial Referencing” at the German Federal
Agency for Cartography and Geodesy (BKG), dealing with the German and the European height
systems, GREF (GNSS reference station network in Germany) and the national quasigeoid model
GCG. He graduated as a geodesist from the Technische Universität Dresden (TUD) in 1990 and
finalized his PhD thesis on the processing and use of water level time series for geodetic and geodynamic
applications in the Baltic Sea in 1997.

Ole B. Andersen is professor in marine geodesy and head of the hydrosphere group at DTU
Space at the Technical University of Denmark which is the national space institute of Denmark.
His activity in the working group has been to provide satellite-based long-term estimates of mean
sea level and mean dynamic topography as a supplement to and for the evaluation of the FAMOS
geoids. Ole is Ph.d. from the University of Copenhagen in 1996 and has since worked on marine
geodesy focusing on development of global reference surfaces for gravity and mean sea surface
as well as ocean tide models.

Résumé

Le Baltic Sea Chart Datum 2000 (BSCD2000) est un système de référence
géodésique adopté pour les levés hydrographiques, l’ingénierie hydrographique,
les cartes marines, les publications nautiques et les informations sur le niveau de
l’eau de la mer Baltique. Il est basé sur les normes géodésiques communes au
Système de Référence Vertical Européen (EVRS) et au Système de Référence
Terrestre Européen (ETRS89). En particulier, le zéro hydrographique du
BSCD2000 est conforme au Normaal Amsterdams Peil (NAP). Le BSCD2000 est
sur le point d’être adopté en tant que niveau de référence des cartes commun par
l’ensemble des pays bordant la mer Baltique. Il correspond à la plupart des
mesures de hauteur nationales utilisées à terre. Le BSCD2000 facilitera l’utilisation
efficace des méthodes du GNSS comme le GPS, GLONASS et Galileo pour une
navigation et des levés hydrographiques précis à l’avenir.
