Within the Protocol Agreement signed in 2005 with the Cadastre Administration (Agenzia del
Territorio), the Friuli Venezia Giulia Region arranged to survey 10% of the Fiducial Points (FP)
placed in its land, and to locate the remaining FPs, linked by the cadastral surveys of the
professionals, in analytical way. The surveys were performed by GPS receivers, integrated by
classical survey methods where the set up of the GPS antenna on the FP was not possible, or the
bad reception prevented the proper use of the satellite instrumentations. From the surveyed FPs
(more than 3500) the coordinates of the remaining linked FPs distributed in the region were
computed. The activity allowed to determine the cadastral point position in a reliable and steady
manner, and to define their coordinates in Cadastral, Gauss-Boaga, and UTM-ETRS89 reference
systems.
