USO DEI PALMARI GNSS PER L’AGGIORNAMENTO CARTOGRAFICO: IL CASO STUDIO DEL COMUNE DI ROCCAMENA (PA)

This work is an example of survey for the map update and run with handheld GNSS and differential corrections data through the network of permanent stations. This case study is about urban drainage systems and lighting subnets within a limited area of the town of Roccamena, Italy. The survey has the primary target the planning of engineering data needed to implement a GIS, the study was performed as mode NRTK with correction VRS, affected, in particular, the wells of public lighting, the wells of white water and sanitation, in addition to the drains around the town, on a total area of approximately 33 square kilometers. Once homogenized the data was developed a Geographic Information System (GIS) with open source tools, paying particular attention to the structuring of the spatial database, designed according to technical rules dictated by the INSPIRE Directive.
