Set of marks in the territory within a specific local area, called geodetic benchmarks, whose location has been measured based on topographic/geodetic techniques and have been materialized on the ground with landmarks or signs, and whose coordinates have been set following the procedure defined by the Integrated Geodetic Positioning Service of Catalonia (SPGIC). These benchmarks are derived from the Utilitarian geodetic Network of Catalonia but are not integrated within it.

The Municipal Topographic Network is constituted by points that represent the vertices of the XTM-LH. The coordinates of the points are in the reference system ETRS89 and projection UTM time zone 31 North and the ortometric level is the result of applying the geoide EGM08D595. Points have some associated attributes that describe them.
