The SPiDER wireless, color manhole scanner from CUES can calculate its position in the manhole shaft by using sensor data to measure its incremental motion. It weighs less than 30 pounds and can be hand-carried to easements or other difficult-to-access sites. The processing computer and battery supply are integrated into the scanner, which allows portability. It collects millions of 3-D measurements during each manhole inspection. The raw data is post processed to a 3-D point cloud that provides engineering and survey quality information on manhole geometry and condition that can be used for structural assessment, pre- and post-rehabilitation analysis, hydrological surveys, as well as general condition assessment. It provides live-video stream and recorded video that can be used for I&I studies. 800/327-7791; www.cuesinc.com.
