  • 3D geodetic network

    Geodetic markers of which the 3D coordinates are precisely known in common Belgian reference systems.

  • Planimetric geodetic network

    Network of marks whose planimetric coordinates are known with precision according to the reference systems which are used in Belgium.

  • G-DOC

    The web application G-DOC provides information on all Belgian geodetic reference points. These points can be used as starting points or checkpoints to determine coordinates according to the national reference systems. three groups of geodetic reference points are available: 3D points, altimetric points and planimetric points.

  • Altimetric geodetic network – Second general leveling

    Whole of marks whose height with respect to the zero mark of the second general leveling is known.

  • GNSS Stations of the Royal Observatory of Belgium

    The Royal Observatory of Belgium maintains several continuously observing GNSS tracking stations in Belgium. The stations are also belonging to EUREF Permanent Network (EPN) used to maintain the ETRS89 and the observation data are available to the public through https://doi.org/10.24414/FST8-P256.
