A surveyor determines the boundary and the tree's location relative to it. An arborist or forester provides an opinion as to its value. In a state lik...

I'm with John on the AP-20. It's not $12k, and it goes on sale from time to time. It is far more than "just a prism". Automatically updates target he...

I use RTK for control regularly. But I never establish control without redundancy and adjustment. RTK in excellent conditions will be dang near as tig...

Implicit in RTK positioning is the assumption that the atmosphere the satellite signals are passing through is the same for both the base and rover. T...

They have. Putting that cap over the top of the post seems like a wise precaution to me.

This is the sort I like best.

That TSC3 is really very similar in size and form to the Leica CS20 which is still being sold, and which I use. My only real beef with the CS20 is tha...

Have you checked your local commercial rent-it center? One that services contractors? If not that, and if you don't mind spending a bit of money there...

I think of F2f as primarily quality control. CAD speed is a side benefit. Nevertheless, I believe that dealing with drawing elements on a 3 1/2" scr...

Donate the books to your local Goodwill. They will eventually make it onto any of the various online used book stores. Much of my library is made up o...

My Canadian wife long critically commented about how Americans dropped the "u" out of english words of this sort just to be difficult, until she was s...
