kbrown,
I have seen data from a stationary scanner on buildings in Perth and it was pretty damn clean. With a moving vehicle though, you are right. It would be interesting to see how much is useful and whether y0u could interpolate it easily. With the SIMPLE GPS and software I use, well, I spend a shitload of time re doing stuff, it aint foolproof to lifes foibles.
I saw a 1 million point pickup on a building front (to check movement against tunnel construction) and it was perfect. Again stationary, AND it even picked up a beer bottle sitting on a window sill, label and all!!! The data download was laborious though, as the software had trouble with that many points.
Still that was 5 years ago, so there may be some merit in it. Great for us Surveyors and good for future modellers I reckon.
cheers bullet
