Along the lines of Kent's comments, I'd need to know how the river changed course between 1930 and 1950. Was it erosion/accretion or evulsion. Assumin...

Been there. Sometimes it's the best option. However, I agree with Mr. Calder. Do your due diligence, make your best determination, any surveyor coming...

I don't think it works that way. In your flow, you haven't communicated to the base any new position, it's still pumping out corrections for 5000,5000...

SBAS - ITRF vs NAD83Some receivers use the WAAS signal with impressive results. My Altus receivers, for instance have incredible precision (about 1 fo...

That's awesome Tommy!

Do you have pontoons? I'd hate to splash down with that rig. 🙂

Any day now I'm told.

I'm friends with Mark, but (other than the beer he bought me last week) I have no financial arrangement with him, so hopefully it's cool for me to lin...

Not much I can add to what Mark has said. The nomenclature in all of these products is kind of confusing, but I'll take a stab at this. The Triumph 2 ...

I've had conversations with some of the software engineers directly who are also geodesists. We discussed what to do with redundant positions (whether...
