The CoPaG and DFLBF databases for Brandenburg, Germany were computed in a cooperation with Ingenieurbüro Seiler (IBS).
With respect to 42/83-network two databases were computed:
CoPaG database Brandenburg 42/83 --> ETRS89
DFLBF database Brandenburg ETRS89 --> 42/83
The figure shows the situation of the meshing design together with the identical points and the accuracy surface.
