Ok guys I need someone to school me on adjusting a traverse. Starting on 2 known pts ending on 2 known pts. CARLSON 2019

The original project consisted of a single traverse loop 1 thru 19 with a spur to 49 set from 1. Closed and adjusted years ago. Now today went into the field with those pts and coords. Set up on 49 bs 1 set 500 thru 508. 507 & 508 aka 16 & 17.

I'm trying to get this adjusted in Carlson compass w/angle balance.

My rw5 starts with oc 49 bs 1 fs 500.....trav trav trav...... oc 506 bs 505 fs 507 / oc 507 bs 506 fs 508.

The edits I made were changing all 507 to 16 and 508 to 17.?ÿ

The pts 1-19,49 exist in the current .crd.

I then choose to adjust compass rule leaving angle balance checked pt protect is on. The closing reference pt field was blank I put in 16 and it pulled the coords for the nez feilds.

Everything good so far right ??

I appolagize i dont have this in front of me im home now so going on memory but I think the next prompt is to choose start pt and end pt or closing pt?ÿ I entered 49 and 16. Then there is a prompt for closing angle or angle balance oc fs. I chose oc 16 fs 17.?ÿ

Then comes all these pt protect warnings about 16 & 17 new and stored. This is where I got confused. I chose to skip current ( leaving the original coords) on every prompt and end up with garbage results.

I'll be happy to post the data and give more details when I get in the office if anyone is interested. Thanks for any advice.

Carlson website has the information to teach you practically everything as well as the instruction manual for your particular version.

Carlson XPort is a product you can download from their website when you have a licensed version of one of their products and it is all about making most any type of adjustment to your raw data and importing and exporting into many different file types.

What you did - renumbering your points from the 500s to match your existing control point numbers is what you would do if you were using Carlson's least squares adjustment program, SurvNet. When doing compass rule adjustment in Carlson you are supposed to keep the new point numbers in your raw data file, and in the settings tell Carlson that point 507 = point 16, etc.

I find Carlson's compass rule adjustment routine clunky, and I don't like having multiple point numbers in play for the same point, so I stick with using SurvNet for traverse adjustments.

  • Got this worked out. As you said Peter leave the #s alone in the raw. In my scenario ref closing pt is 16. Loop is start at 49 end at 507. Angle balance shot is 507 to 508 ref closing angle is 16 to 17. You do end up with 2 pts on the closing pts 507/16 and 508/17. My procedure is to delete 507&508 as the differences were both less than 0.01'. Nobody wants 2 pt #s on there trav. pts.
