Applications and Technology “Mobile mapping represents a heterogeneous type of sensor integration consisting of navigation sensors as well as imaging sensors, together time synchronized and mounted on a common platform” (Schwarz & El-Sheimy, 1996) • • GPS IMU Odometer Barometer Multiple cameras/video Laser scanner Special sensors (georadar, laser profilometer, etc. ) Sistemi Avanzati - Roma 2

Applications § Asset management and utility inventory (build asset inventories and keep them up to date) • Road side equipment : street furniture, road signs, speed limits, road lanes, marking, traffic lights, bus stop, pavement types, vegetation, flood ways, culverts, drains, kerbs, guttering. • Verification of existing assets and measurement of asset dimensions § Planning and studies (a decision support tool) • Follow the evolution in your network: visual inspection and road geometry • Organize scheme design and traffic signals, sign replacement program • Decision support tool for lane closures and access • Creation of a geo referenced imagery database allowing to measure the evolution of the network Sistemi Avanzati - Roma 3

Applications § Network Operation • Visual inspection of network and road geometry • Measurement of lane/footpath widths, height clearances and set-backs • Graphical aid to works specifications • Review existing highway data set, surface condition • Planning of responses to events and diversions occurring on the network • Follow and control of subcontractors acting in the network § Disaster management, planning and response • Emergency management plan • Adapt intervention planning with data collected after catastrophe • Inventory the damages after catastrophe Sistemi Avanzati - Roma 4
