Abstract :
We have developed a vehicle-borne laser mapping system (VLMS), which consists of Laser Scanners, Line Cameras, GPS and INS. The system uses range data, scanned by the laser scanners as the main source of 3D data. In this paper, we present about the development of VLMS, which includes the system architecture, calibration and geo-referencing of sensors and positioning devices. Next, we present the extraction of some basic features like building surfaces, road surfaces (man made features) and trees (natural features). Finally, we will show how these features can be used to build 3D urban GIS database, which will assist in various applications as mentioned above. Besides, we will also discuss about the capabilities and difficulties of such a system
