Hello,
I would like to compile a list of options for reducing coordinates based on multiple observations on traverse points ending in a closing shot.
I need to see a error of precision (e.g. 1:10000) based on misclosure and traverse length.
We used to do a lot of this years ago but I don't know where to start looking for options so I thought I'd come here. My Leica rep referred me to geooffice options that I didn't like. I liked the old DOS based processing software we used to use and wonder if there is any around that will still work for me.
I would like to find PC software specifically for handling survey data, converting file formats, processing etc.
We have Civil 3D but I don't like the options they present either, I would prefer a simple, cheap solution.
Same as it used to be is probably not an option these days eh 🙂
Thanks,
Pete
Download the Traverse PC demo and look at it, that software was written by surveyors working out of their own active Surveying Office, they started out using Dos and still have an active Surveying business.

A Closing Shot Is Inadequate.
You need to occupy all points, observe all angles and distances both ways.
It is called redundancy.
Anything else is nonsense.

Star*Net is a great way to process traverse data.
If you have cross-ties it can include those too.
Plus multiple observations to a monument that you didn't occupy.

Yes to Star*Net, but I'd want to make sure that someone somewhere has finally been able to write a functional Leica > Star*Net converter. Just because Hexagon owns both Leica and Star*Net doesn't mean that you shouldn't check to see.
Traverse Computing - (Long)
Pete,
I feel your pain, buddy!
You are describing things the way they were when I started surveying too. But now it is different with all these computers and softwares and CAD and robots and DC’s and GPS…..
Welcome to the 21st Century!
My suggestion is that you reach down deep inside yourself and put on a new learning attitude. It is going to take work and it is going to take you some personal time, but you can do it. You will be better for it. Paul had to do this. Kent had to do it this way. I had to do it this way. I don’t know if Dave did or not. I am suggesting that you get Star*Net and you get a tutorial and you start working some examples and work up to doing your own survey control with Least Squares. You can use software you already have too, but that may be more difficult for you to learn because of all the other software intricacies connected to it.
You see, Pete, others of us have already gone down this pathway. You need to go down this pathway too. Is there someone in your area that can work with you as you learn Least Squares? That would make it much easier for you and you would benefit greatly from having a mentor to study with. You would catch on faster. You would learn more about the options of the program. How about asking around at the next Chapter meeting to see if there is someone knowledgeable in Least Squares that could get you started? If that is not available to you, how about asking for a Least Squares class at the next State Conference that you attend? If that is not available, you may have to just start asking the questions here to get yourself up to speed.
I think once you start working with an error ellipse and take out one measurement and rerun it to see the effect (or add a cross tie to a traverse), you will start seeing the worthwhile uses of this concept. It is truly a great tool to have in error analysis and looking for problems in a survey. When you look at the ALTA specs, you will see that they call for accuracy standards that have nothing to do with 1:10,000 or 1:15,000. You will then be able to sign that survey knowing what accuracy standard your work actually meets. Right now you probably don’t know, you just think it is good enough and sign off. You are not alone here in doing that.
Take a deep breath and dive in. Because you need to. We are here to help when you need it. We are here to help you stay motivated to accomplish this. You will be better for it. I submit that your surveys will be better for it. Thanks!

I'm a big StarNet fan, too.
Carlson Survey has lots of tools for importing data from multiple sources and performing adjustments of various kinds. Plenty of other calcs, too. That may be a good option for you.
FWIW, those old DOS tools only work well in the Kodachrome of your memory. I have a DOS utility that I have to use to convert Topcon static data to Rinex. It's both a trip down memory lane and a modest PITA. I works great, if I get all the syntax and switches exactly right.
Thanks
A couple of relevant replies in there, thanks for the input.
I have checked out Traverse PC in the past, and Microsurvey came up as an option as well but I have ended up with the Carlson Civil Suite to serve me. It includes the Carlson Survey package. It is a bit more than other options, but you get 3d and civil functionality.
Thanks to all of you who had positive, relevant and meaningful input.
Pete
