Hmm. I have a topo foot for my prism poles that is the same height as the pointed foot. I've had it for at least twenty years. It's really not a probl...

Here are what the uncertainties looks like with vectors from Pt. 1 to Pts. 6, 11, and 17 in addition to those to 2, 3, 23, and 24.These use Conrad's i...

So, using an instrument with the very low uncertainties that Conrad suggested should give the following uncertainties of points along the traverse if ...

Here are the predicted uncertainties of the control points connected by the traverse if the following instrument uncertainties that Conrad asked about...

Okay, so GNSS vectors with an uncertainty of +/-8mm (= 0.026 ft. in N and E) to all control points on the traverse that are then connected by conventi...

So, if just two more vectors in parts of the traverse where the uncertainties are larger makes such an improvement, what would adding GNSS vectors of ...

So, one obvious improvement would be to add GNSS vectors of the same 8mm quality (standard error of 0.026 ft. in N and E components of coordinates der...

One approach would be to survey Pts. 2 and 3 and Pts. 23 and 24 at the beginning and end of the traverse, respectively, to get an approximate starting...
