In your example you are relying entirely on the stochastic model (error estimates) to yield an estimated error analysis (not an actual error analysis)...
Let me revise that.> CONCLUSION:> Least squares adjustment is not possible needed."...As an example, consider the determination of a distance b...

You know, with TDS survey pro one can log at a given elapsed time with RTK. Perhaps setting the RTK rover on a fixed height tripod logging and storing...
Shelby, you just need to start a leveling campaign and put a RESET elevation on that puppy!
Oh yeah! West side, different benchmark. We tied into the "west" BM.
I know that mark! There is (used to be) an Army Corps bench mark by the boat landing just north of there.
As far as I know yes. You try contacting the folks doing the training to see if you could organize the training in your neighborhood. Find a day and v...
I just noticed that this cap is mis-stamped! Should be "R11E"
I wish!Perhaps the R10 was aesthetically influenced by the LOCUS!
