I would like to see a side-by-side comparison in Time vs. Cost between Photogrammetry and Laser Scanning, as well as the difference in accuracy. The gap between the two isn't as wide as it used to be, due to 3D scanners getting cheaper, but there has to be a reason SCS hasn't gone that route, already..
Maybe, like me with GIMP, SCS just keeps doing things the way they know how to do them because they don't see a reason to change, or relearn.
