Site Scanning and Mapping

VEAR acquires one of the first FARO Focus3D X 330 laser scanners.

The FARO Focus3D X 330 is specially designed for outdoor applications due its small size, light weight, extra long range, extended scanning possibilities even in direct sunlight and easy positioning with to the integrated GPS receiver.

Laser Scanning Brings New Asset to Accident Investigations — and Surveyors

Laser Scanning technology is revolutionizing many aspects of surveying and applied measurement, but it’s been especially game changing in the rarefied niches of forensics and accident investigation. The main strengths of scanning — speed, safety, accuracy, comprehensiveness, and the ability to return to the same data set and make new observations — serve forensic engineers especially well. Money is also a factor: when so much is riding on a court case, the extra costs associated with adopting new technology don’t seem especially significant.

VEAR uses advanced equipment to map your sites. By using its laser-based, reflectorless mapping station, accident sites can be documented to within 1/4 inch at a distance of 1000 feet. As of January 2012, VEAR uses a laser equipped Sokkia SET5X map station with a maximum distance of 16,400 feet. Reflectorless technology allows us to set up on the side of a road, and measure evidence without standing in the road holding a target. We have shot points along the edge of the road almost a mile long to create a profile of the road. An onboard data collector allows viewing the site drawing as it is being measured to help ensure accuracy and completeness. Wireless connectivity allows the data file to be transmitted to the office from the side of the road.

Rendering

After a site is mapped, the data collector is downloaded and a scale drawing is rendered using AutoCAD, Rhino, SolidWorks, 3d Field, or MapScenes Pro depending on the circumstances.

Printing

Scaled site maps can be printed on an HP DesignJet 800 PS plotter capable of producing maps up to 42 inches wide, and as long as necessary. The current length record is 10 feet.

Benefits

An accurately reproduced scale site map is vital to any accident reconstruction. The overhead view of the site allows accurate measurement of relative distances within the site. The scale drawing can be used as demonstrative evidence and is a necessary foundation for simulations and animations. Our experts have performed over 1000 mappings of crash scenes, vehicles, power lines, factory equipment layouts, and sidewalks.
