Next silly question about the Nikon. It has options for Curvature and Refraction of OFF, 0.132, and 0.200 but I can't relate those numbers to any valu...

My wife's family land is a mess in that the legal parcels do not line up with the creek, road, and usage, among other problems. She and her brother d...

The type of foot is as much part of the definition of a projection as the false northing and easting. If your SPC or LDP was defined with US Survey fe...

People often forget how much averaging it takes to get angles accurate to the instrument spec. The definition isn't intuitive.

What are your state's accuracy standards? The 0.01 ft is most likely a requirement for resoluttion expressed on a plat, but the accuracy spec will be ...

Moe - that's pretty much what I did, using two "known" points. Lurker - I don't suppose there is any way to get past the "Tilt Telescope" message with...
