Thanks for the explanation. So what you're saying is, the TS (therefore, the ZA) and the prism rod (therefore, the rod height) aren't physically chang...

There is no software involved. I'm just interested in the geometry of a hypothetical situation. Because of this I learned something new in Excel. I op...

Got it.

Was just on TS for topo. Maybe my thinking isn't valid. If you raise or lower your HI, the ZA changes if you point at the prism.

Hope it's interesting. Yes, it was. Florida SPC Zones:Lambert, 1 zoneTransverse Mercator, 2 zones

@talderson Looks like the good stuff costs money. It's mostly about self-study. You have to be motivated and disciplined enough to set aside time to...

Go to a library, public or college, and get a textbook on basic surveying and mapping. Study chapters on sources of error (personal, systematic, natur...

I can only make my software display four decimal parts of a second. What software are you using?

If you get up that way let me know. Thanks. I really appreciate the invitation.

I assume its semi permanent stations located throughout your areas you work. We use what our GNSS network provider describes as: 1. A multi base d...

Is there an airport nearby? No, but there is an ER.

Otherwise, the lot is land locked and of value only to someone who has access to a public road. Ingress and egress.

The 40’ radius cul-de-sac was never built and the road is now a private road in a multi owner subdivision. So, the 50' ROW of Southwood Circle abut...
