Topo Scan

Post by mtyler1 » Sat Nov 10, 2018 10:51 pm

I'm asking for advice from you more experienced scanners. Bidding on a scan to be done in conjunction with a survey. Area is the perimeter of a industrial center, surrounded by a fence, 1900 feet x 1500 feet. Very gradual grade, good line of sight. I've done mostly structural or vehicle scans up to now, and this will be something new. I run a Faro Focus 330x.

No need for colorization. How far apart should I do the scans? Do I need targets? Is there anything I need to be taking into consideration for this type of work?

Thank you in advance for any responses.

I would suggest Targets. If I were doing this I would do my scans at minimum every 100ft but probably more often to see all the areas around the building with spheres in-between the scanner setups 50ft from the scanner. We also have an x330. If you can use an elevator tripod and get he scans higher in the air you may be able to spread it out a little more. You also need good survey control to constrain the scans to for Topo work. At least one every 500ft but I usually put mine closer to 350ft apart now.

Thank you sir. Another question: What's the coldest temp you've been able to operate in? Any suggestions on how to extend that range?
