Laser Scanning is a very useful technology for 3d modelers. It is a one kind of survey device that facilitates the users to get exact measurements in complex surroundings. The device gathers survey data points at the speed of 50,000 points per second and contains an successful range of 400 to 500 feet. Just arrange scan setups within the facility and you will get the complete 3D model that can be applied to generate 2D civil or architectural drawings, 3D computer models as well as final survey documents.
Watch the following live demonstration through youtube which shows how Haskell, a leading USA based architecture, engineering, and construction firm, has recently applied 3d laser scanning technique in a water retrieval project.
