National register of base geodetic, gravimetric and magnetic control networks (PRPOG)

In the National Geodetic and Cartographic Resources are collected and available information and data (including archival) of basic geodetic points for the entire country in the networks.

Coordinates of the horizontal basic network are available in the spatial reference system "PL-ETRF89" or  "PL-ETRF2000" and the national coordinate systems,„PL-1992” i ”PL-2000”.

The heights of levelling network are available in The Height Normal System PL-KRON86-NH i PL-EVRF2007-NH. For some points the ellipsoid heights are definied in according to the ellipsoid GRS 80.
