References

The EGiB data (Ewidencja Gruntów i Budynków) consist of 2 primary layers: cadastral data (parcels) and buildings footprints. The data is maintained on county level, which results in 380 units (different sources of data). It may contain additional layers like points of detailed horizontal and vertical geodetic control network ("osnowa_pozioma" and "osnowa_pionowa" respectively).
