Adjustment Software

What are most using for adjustment software? When adjusting conventional closed and open traverse loops.

I can't speak for "most" but I can tell you that all of the reputable surveying software packages have adjustment routines built in.

Having said that, if you are doing ALTA Surveys you must use a Network Least Squares package of some for to determine whether or not the accuracy standards have been acheived.

I use (and teach) the SurvNet package that is built in to Carlson / C&G.

Finally, when you say "open traverse loops" I assume you mean traverses that begin and end at known points.  I know it sounds silly to have to spell out that assumption but you'd be shocked at the numbers of people who have come to me wanting to find a way to "adjust" open traverses.  I even had one guy who had a job where he set up one stake and just always backsighted that one stake as he traversed up a ridge.  He was agast that I couldn't tell him how to turn his crap work into golden data.

I've used StarNet Least Squares for years.
It's great for conventional, and or adding in GPS observations. I know quite a few people that use it.

I've used the least squares adjustment software embedded in AutoDesk Survey for years.  I've also used a few homegrown software packages  - one written for Maine D.O.T. and one for a private firm.  

The Autodesk software is a little limited (no separation of the z into a 1D network for example - you either have to run a 2D or a 3D network).  With that being said, it still does the job for the little traverses I run around here.  

I like Star*Net a lot.  It's fairly easy to use and is reliable.

My newest version of Microsurvey also has least squares, but I haven't used it yet.  I need to try it out.  If it's like the other routines in that software, it will take one or to tries to learn it, but then it will seem incredibly easy and much more logically designed than anything that has ever been in DCA/softdesk, LDD/civil 3D/whatever the new name is this year.
