The CoPaG and DFLBF and DFLBF databases for Karlsruhe, Germany, were computed as a project of the town survey agency of Karlsruhe.
With respect to the classical German DHDN-network two databases were computed:
CoPaG database Karlsruhe DHDN --> ETRS89
DFLBF database Karlsruhe ETRS89 --> DHDN
The figure shows the situation of the meshing design together with the identical points and the accuracy surface.
