Good point about the BM possibly being on 29 datum. If I were doing what the OP is trying to do I would check the same published benchmarks used in th...

The OP difference is significantly more than the mentioned local differences that can be obtained using the RTN. RTN's adjustments are global in natur...

I spent a little more time testing the theory that a translated datum was used vs. the non-translated NAD83 datum of any realization and any geoid com...

It may be a datum setting in your field software. On mine I tried a couple settings in CA zone 3 and got 1.8 ft difference around San Jose. The softwa...

The abbreviated description from county is W 1/2 OF W 1/2 OF NE 1/4 SEC 18. BLM patent was 1879 W 1/2 OF NE 1/4 SEC 18 containing 80 acres.

How would they know how many acres they have? The real estate agent? By looking at the original government survey I suppose.

Wow - why must we make things so complicated? Would I have Star*net output a "Ground Coordinate" file, and put those into the DC? No! Your cont...

tolerances are specified outer limits of acceptability. The outer limits of your angle sets are 7 seconds. I wouldn't want the software to treat the ...
