Road’s Cadastre and Safety Evaluation Gis Realised With Data of a MMS Vehicle

Performing road’s survey with a MMS vehicle a georeferenced database is created. This database contain several data: road’s axis, road’s width, tangent grade and cross slope, curvature, vertical and horizontal signs, etc. This paper will present GIS building methodology starting from MMS collected datasets. The data, as requested by Italian road’s cadastre law, are in tabular form and describe segmented attribute of road. A graphical GIS representation permits to give support to technicians who work on road’s management and on road’s safety control. As example will be present a survey realised by Department of Civil Engineering, Seat of Topography and Photogrammetry – Pisa University, using GIGI One MMS vehicle of Excellence Centre for Telegeomatics Research of the Trieste University. The survey is related to the s.s.1 Aurelia near Livorno.
