I had the occasion to combine an old 2003 laser scan set with some current data. I expected the 40° square windows scans, but, what I didn't expect to see was our old RTK broadcast base trailer, those big old ground planes and the old survey van. If I had given it a thought I might have expected them, but, they were cleaned out of all of the screen caps. That poor trailer was dragged down a State Hwy on its side by one crew, flipped into a ditch by another, had the axle basically come out from under and each time it was repaired better than it was before. It was one beefy trailer when I sold it to a contractor several years ago. I also like how no one tried to get out of those old slow scans, there were lines of "walkers" everywhere
I didn't even know this was happening back in '03.
You happen to remember how many points a second the unit collected??
I remember; circa 1999, the Leica rep borrowed your gear and came down and gave us a demo.
It was fairly impressive, for the day. He picked up 100,000 times the data, in 2 hours, that my 2-man crew could've done in 3 days; and had it back in our boardroom, showing our engineers how easy it was to turn into a map...:-D
Later; I saw the guy at a conference, showing off the scan he made for our demo...
Thanks for the flashback!

It was this great big box that sat on top of a heavy duty tripod. It scanned a 40deg x 40deg area up to 100 meteres away. You moved the box manually and needed a 20% overlap for each scan. You probably needed 10 scans or so to go 360.
The rep claimed it was 50,000 per second.
I really don't remember, but, it was nothing compared to today. I was surprised to see that the 2003 stuff was cloud stitched as I though that was a few years later
I sure didn't seem that fast in retrospect ...
