"StreetMapper Bridges"
Automated Data Extraction for Bridge Heights Using LiDAR

Presentation Track 6B Sept 13 at 3:30 pm

StreetMapper Bridges automates processing of 3D laser scanned measurements using complex statistical algorithms to identify road surfaces, isolate bridge data, identify lane markings and remove noise - for example traffic on the highway. The application then extracts cross sections from the data and calculates clearances and other user defined measurements. This automation enables large-scale use of laser mapping by eliminating manual inefficiencies and reducing the chance for error. The StreetMapper 360 technology is proven survey grade accuracy with final positions of better than 0.03' using correct field procedures.  Relative positional accuracy of better than 0.02’ in raw data. This makes Terrestrial Mobile LiDAR Scanning (TMLS) a very useful tool for bridge height surveys.

StreetMapper Bridges utilizes Allpoint Systems’ Perception Engine™ a software processing system that batch processes entire directories of 3D laser scanned data. The Perception Engine uses a hybrid of software tools that mix automation (for time consuming repetitive tasks) with streamlined user interaction (for efficient high level decision making). The software is already in use in tunnel mapping, robotic wastewater pipe inspection and other terrestrial laser scanning projects. The combination of TMLS data collection at traffic speeds by Terrametrix and automated extraction with StreetMapper Bridges addresses traditional unsafe data collection methods and time consuming data extraction.

Terrametrix President, Michael Frecks, and URS Corporation Senior Project Engineer (GISP), Kouroush Langari, spoke jointly about GIS Benefits, Value and Achievments within Government and Private Sector Organizations. The SMART District is proposing implementation of passenger rail service along an approximately 70-mile existing rail corridor extending from Cloverdale in Sonoma County. The project also includes construction of an ancillary bicycle/pedestrian pathway adjacent to the railway. Utilizing ArcGISv10 and AutoDesk Civil3D, and Integrated Project Delivery (IPD) model will be developed to assist Planners/Engineers?Contractors to ultilize the same model in their respective disciplines. Using ArcGIS geospatial analysis the getechnical boring logs were mapped along the 70-mile corridor and were served utilizing ArcGIS API for Flex version 2 to be distributed to the stake holder.
