Points of the Horizontal Geodetic Control (PBP) include points of the fundamental horizontal control (ZPBP) and points of the minor horizontal geodetic control (PPBP). They are administered by the Land Survey Office or, for certain categories, by the respective Cadastral Offices.
Points of Horizontal Geodetic Control are reference points for accurate location of geoinformation in the Datum of Uniform Trigonometric Cadastral Network (S-JTSK) at the territory of the Czech Republic. They are divided by importance and accuracy of coordinates setting into Points of Fundamental Horizontal Geodetic Control (FHGC) and Points of Minor Horizontal Geodetic Control (MHGC). Points of FHGC are part of Geodetic Control of the Czech Republic that creates a reference frame of coordinate systemes at the territory of the Czech Republic. Points of MHGC create a reference frame of the S-JSTK where part of the points (approximately 3100 point of selective maintenance network) are also a part of national realisation of European Terrestrial Reference System 1989 (ETRS89) reference frame realisation.
