Abstract. In the last two years the Lynx Mobile Mapper has become the new lidar solution developed for surveying large areas that are impractical with static lidar sensors and require an accuracy and resolution that exceed airborne technologies. The system allows the scanning at a speed up to 100 km/h, obtaining accuracy better than 5 cm with an up to 7 mm resolution. Therefore, this solution proves to be an excellent tool for surveying city centers, highways, railways, thanks also to a very fast, safe and accurate data collection. This paper will present two applications:
1- The survey of the entire ancient city center of Brescia (Italy) with it medieval castle, the narrows streets and the main squares. It also has been run a test to survey with the Lynx the tunnel that go underneath the castle and compare the result with a static laser scanner survey,
2- The survey of the Calatrava Bridge on the A1 highway. The central bridge, which crosses over the high-speed rail line and the A1 motorway is composed as a single symmetrical arch, placed longitudinally, which rises to a height of 46m. During the survey the two A1 motorway carriageways have been scanned and the upper part of the bridge for a complete 3D model of this structure.
