the geological part could have been a miscommunication. My wife over the years has told people that I am a geologist (instead of geodesist) and an ast...

abolish all of the state boards and have a national license.

Stadia set in meters?Actually, what I think Dave was referring to is that there were some instruments that had stadia hairs that were 333:1 instead of...

Stadia set in meters?The stadia hairs are set as a ratio, they are unitless. A typical level has stadia hairs set at a 1:100 ratio, so if you intercep...

Kent: my understanding of the manufacturing process (limited) is that they test the instruments, and if it is better than 5", they call it a 3" gun, a...

Kent: I use a Trimble S6 high accuracy (1", 1 mm+1 ppm). Since you seem to be a stickler for accuracy, I think you would really like this instrument. ...

This really depends on the geometry of each of the individual setups (the four random points) as well as the geometry of the known points. A perfect a...
