Traverse Adjustment in Cad

Hey guys, I was wondering how does everyone approach the traverse adjustment for your surveys?

I have in the past used the Survey Pro software in the collector to run up a closure and then adjust it in there and just import the adjusted ascii file into my drawing and go to it with mapping.

I have also done it with the raw data in cad by converting to a field book file and importing and adjusting in cad but it seems to limit you on what you can do with the data collector. For example we always have to go back and change point description errors in the raw and rod height busts. It also doesn't like any distance offset shot. It will do angle offsets but thats all.

Is there a way to do it with just the point numbers in an ascii file?

Thanks,
Harry

I am certain that you could do some sort of adjustment in CAD from just the points in an ASCII file. But to what end?

A valid adjustment needs information that you cannot supply from just the coordinates alone. You need to identify things such as your linear closing error and your net accumulated angle error. Those bits of information could only be inferred from the basic coordinate data if they could be arrived at at all.

For the least squares adjustment referred to in another thread, you need redundant observations. Those are the most minimal of objections to that approach. I sure there are others.

provided the survey was done without scribner's, and you use different numbers for same points, you can close a traverse from the ascii alone, but with all the packages, why?

You ask a lot of CAD questions. Maybe you should change your username to Harry Plotter.

I see what you did there.

I like having some sort of printed report in my files. So I'm going to go with the download and adjust in the office method most of the time.
