Photogrammetry

        Evidence useful to a reconstruction or investigation is sometimes lost or left unmeasured.  Photographs may be the only source of this data. Our computer systems allow us to retrieve much of this information. Under favorable conditions, our measurements are highly accurate (within inches). Common uses of this technique determine:

• Size and position of skid-marks/gouges that are no longer visible
• Rest position of vehicles that weren't measured at the time of the accident
• Vehicle crush of vehicles no longer available
• Position of road lines that have been changed since the accident
