It is to find out what the error is (diff between "true" and computed coords)...i just want to know if there is any program/software to do the cals for me. I calculate by hands then input the values into microsoft excel manually and that is hassle.
I'd still recommend Copan from UGL (though i'm biased).
It can calculate, and adjust, closures for "raw" traverses (ie, those having backsight and foresight angles, vertical angles and slope distances), and for "reduced" traverses (ie, those having bearings and horizontal distances). And it's free.
I also still don't see why you can't use "any old" survey software. Does anyone know why it might be difficult to solve LAguy's problem using other software?
LAguy,
I'm not exactly sure what your question is.
Are you trying to determine your closure, or are you trying to balance your traverse?
One CANNOT "reduce one's closure error to zero."
What one CAN do, is balance the traverse by DISTRIBUTING the closure.
There are some fairly easy equations that will do this, and there are a number of software programs that will do this as well. Some of the software programs are free, some are quite expensive. Some use methods that are no longer considered to be valid.
If you can give me some more information on what you're trying to accomplish, I'll try to help you out.
LAguy,
Check out underhill's copan software, or his online area calculator. It looks like either one should work for you. Both are available on this link:
