The Great Wall of China is one of the largest manmade wonders of the world, comprising many different and irregular structures. We employed airborne Lidar to produce highly accurate digital elevation models (DEMs) to identify areas requiring repair. A terrestrial laser scanner mounted on a tripod was used to improve the terrain model, especially for surfaces covered with dense vegetation. The combined use of airborne and terrestrial laser scanner produced DEMs with accuracies better than 10cm...

Can you obtain survey-grade accurate data from a mobile scan system going 45 mph? Yes, indeed, says Mike Frecks, principal, Terrametrix. As a surveyor, Frecks thinks about precision constantly. The current leg of his career focuses on civil transportation infrastructure, including highway and railway, and how 3D laser scanning technology can provide survey-grade accurate, on-the-fly data while keeping operators safe from the dangers of traditional roadway collection methods. This past June, he and his team proved this possible during an 11-day mapping excursion in six cities. They used 3D Laser Mapping’s and IGI's StreetMapper, with a reported accuracy of 8-13 millimeters, final position...

North American cities have been documented at speed using StreetMapper, using vehicle mounted laser scanners to capture highly detailed and accurate measurements at speed. The technique was developed and supplied to Terrametrix by UK based 3D Laser Mapping and Germany based IGI. Using StreetMapper Terrametrix completed a 3,690 mile, 6 city tour in just eight days, capturing highly accurate 3D models of urban highways, interstate, trolley routes and a prestigious international sporting venue and even taking part in a national competition to collect highway asset information...
