UNIX for Beginners Questions & Answers

Thank you! Yes, I have looked at some of it but I was not aware of quite a lot of it. I had not seen that specific site. That gives me a starting point for doing some research at the least. There are also a number of emerging professional publications for the surveying & mapping communities that I want to look at. Architects still use feet & inches which has been obsolete for 100+ years. They live in a different world.
The problem is getting coordinate points produced in co-go & collected in the field to interface with cad that will label the lines with bearings & distances & do such things as create line tables. Geodetic positions take the curvature of the earth & the convergence of the meridians (mapping angle) into consideration. The advantage being that the position is no longer totally dependent on physical monuments once tied to a geodetic datum. Found original monuments still govern by law in most jurisdictions but replacing them once destroyed can be a big problem. Calculations can be done in a separate cogo program or it can run inside of cad. Strong coordinate geometry capabilities are imperative.
