Real-Time Update of the Road Cadastre in GIS Environment from a MMS Rudimentary System

The local authorities that are responsible for the management of road infrastructures must have by law a Road Cadastre by realizing one from scratch or updating the existing one. The Italian road network is spread over 160,000 km of state and provincial roads, so in the face of an efficient solution in terms of costs/performance, a rapid timetable is required for the data acquisition and the construction of the system. The elements of the territory represented in the GIS for the management of the Road Cadastre, on the one hand are characterized by the high mutability that affects both their position and the attributes necessary for classification; on the other hand, the integration of the GIS is only possible through a process of continuous and constant updating of the database. This note, taking up the experimental activities presented in [1] concerning the preparation of an MMS for automatic driving, uses only some of the equipment appropriately predisposed (GPS - GIS), integrating them with two low cost cameras. This in order to test a rudimentary MMS for the updating of the Road Cadastre that through the realization and implementation of suitable software allows to obtain appreciable and interesting results in terms of identification acquisition and transposition in real time on GIS system of elements of the territory for the management of the Road Cadastre. In fact, the proposed system allows real-time recognition (via computer vision) of road artefacts (drains, grids) and vertical signs, as well as the subsequent geo-referencing of acquired frames and automatic transposition in GIS environment (thanks to a dedicated software for updating of the Road Cadastre).
