Abstract: Points of Gravity Geodetic Control - contains only point of fundamental Gravity Geodetic Control, whose administrator is Land Survey Office.
Purpose: Points of Gravity Geodetic Control are reference points for accurate location of geoinformation in the Gravimetric Datum 1995 (S-Gr95) at the territory of the Czech Republic. They are divided by importance and accuracy of coordinates setting into Points of Fundamental Gravity Geodetic Control (FGGC) and points of Minor Gravity Geodetic Control (MGGC). Points of FGGC 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 MGGC create a national realisation of the S-Gr95 reference frame.

Other information: The S-JTSK (Ferro) / Krovak datum (EPSG code 2065) keeps the axis orientation defined for Křovák´s univers conform conic projection where the X axis has positive values southwards and Y axis westwards. Location of the Y,X coordinates origin is, in case of EPSG 2065, related to the Prime Meridian of Ferro (contrary to EPSG 5513, where Prime Meridian is Greenwich).
