Does anyone know where I can find a document of some kind for field personnel, and also for project managers, defining Best Practices for laser scanning.

I'm looking for something saying how many targets should be in overlapping scans, how many control points for georeferencing, how far to keep the truck away from the scans, that sort of thing.

We're just starting out with a Trimble X7 scanner and I'm having way too much trouble getting my scans to register  to each other.

We do mostly highway work, and I'm having trouble finding enough well defined features for registration.

I worked in road construction a long time ago, but I remember that there should be a station every 8 meters. If you have long leg tripods (3-4m), you can increase it to12-15m, because the overlap can be increased. Control point: every 100 meters   on the opposite sides of the road. Use 4 min and high sensitivity settings. These are my experiences and my advice has no scientific basis.
