I'm trying to employ it on every case, whether for actual documentation use or for my own continued training... and each case presents it's own unique challenges! I'm going to "sanitize" some of the names and locations, then put a gallery of scaled CAD diagram files on my website, with each diagram derived from photogrammetry-based documentation. Recent cases include a freeway crash site that could not be measured with traditional tools, a pedestrian fall site in which a sidewalk was found to have a subtle ... but significant... change in grade, and a vehicular damage case in which the impact angle became a critical element. I'm finding this "live" use of photogrammetry to be a unique tool in my crash-reconstruction arsenal. George, I’m continuing to enjoy outstanding results with the iWitness photogrammetry program.

Mr. Bruegge also offers a wealth of knowledge in other areas of forensic image examination and analysis.
