Geodetic Data Base

The Geodetic Data Base comprises information on reference stations, including their coordinates and supporting data, which, in turn, comprise the Brazilian Geodetic System – SGB.

It is materialized through the groups of stations that make up the following networks:

Altimetric:

    Level Reference – RN


Planimetric:

    Satellite Stations GPS and DOPPLER

    Polygonal Station – EP

    Triangulation Vertex – VT


Gravimetric:

    Gravimetric Station – EG

The information about coordinates is available in the SAD69 (up to February 25, 2015, according to R. PR – 4/2012 and R. PR – 1/2005) and SIRGAS2000 reference systems.
