  1. Innovative low cost technologies and services forVideo Mobile MappingX International Scientific and Technical Conference“From Imagery to map: digital photogrammetric technologies”20-23 September 2010 – Gaeta (Italy)

  2. 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

  3. 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

  4. 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

  5. Technologies • Traditional technology • Dedicated and specifically fitted vehicles • High quality/accuracy and expensive equipments • Complex devices require skilled operators • Two or more people (driver+ system operators) required during the survey Sistemi Avanzati - Roma

  6. Innovative technologies • Metric panoramic images collection from street level(earthmine) • Portable standalone video mapping solution(imajing) Sistemi Avanzati - Roma

  7. Innovative technologies - Portable video mapping • Surveying solution for transportation network • Portable device with high resolution imagery fully positioned and oriented • Software suite for processing field data Sistemi Avanzati - Roma
