Probably. See Craig1971s thread today about transitioning to C3d. An fbk file is a txt file, so it is easy to edit. It will contain the station setup point number and the backsight point number. Edit as necessary and import.

I've never run TopSurv of any generation but I do use Magnet. And Magnet allows you to make changes like this in the data collector and it recalcs the results. So perhaps you can fix your mistake in the dc.

I use Starnet in the office to deal with raw data and this sort of mistake is easy to fix there. Other office cogo packages also will.?ÿ ?ÿ

Just remember to make a backup copy before tinkering with any raw data file in case something goes wrong.

That is always a good idea, but don't be overanxious about it. You can recreate the fbk file from the raw data file and/or reexport the raw data from the dc if things go completely sideways.?ÿ ?ÿ

I donƒ??t have an answer for your C3D question. And this is not an ƒ??Iƒ??m better than youƒ? comment. We all make mistakes and we all try to avoid making them twice. So I have to ask, how could you shoot multiple side shots with the wrong occupation number? This is the question I would ask my PC or I-man. My SOP is to setup the instrument and shoot the backsight for a check. Those residuals should be low. Very low. If not, Iƒ??m not ready to survey. Iƒ??ve seen it happen before. Evey time it blows my mind since I have been doing backsight checks from day 1. Not only do I do a BS check at the start, I will check back in every so often if I am taking a bunch of shots from the same setup just to make sure Iƒ??m still good. I thought everyone did this. But maybe not. Something to consider for sure.?ÿ

Say you have two control points, 1 and 2. If you occupy either of them and back sight the other there would be no "error".

This is only true if 1. You are not using elevations, or 2. The points have the EXACT same elevation.

You can always take the whole group of points and translate, rotate, and move up or down as needed.

I thought everyone did this. But maybe not.

Almost everyone claims that they do it. But it is super easy to get complacent about really looking at the values.?ÿ?ÿ

@mark-mayer?ÿ

Thanks Mark. Magnet looks like more of a hardware upgrade than software. It's likely that function exists in topsurv. I'll dig around. The fbk suggestion sounds like a foolproof fallback.

?ÿ

@bill93 No doubt.

There are a dozen ways to fix this.

Yes, TopSurv v7 does allow you to edit the raw data.

You could download a demo version of Magnet Field and do the same.

You can export to raw data and make setup changes in many Cogo apps such as Magnet/Topcon Office, InRoads Survey, Carlson Survey, Civil3d.

Appears the younger generation only work with cartesian coordinates. They don't seem to maintain the raw data anymore, or just don't know-how. A sad fact.

I've been using a total station to complete a "topo assignment"

@bushaxe From this statement I would think @cworld29 is a student. Your comments have merrit for an experinced crew, but this student seems to be learning the hard way.?ÿ

There are many ways to learn. Unfortunately I have learned a few things the hard way myself. Itƒ??s very reinforcing.

I'm kind of amazed that people use the text or coordinate file from the DC.?ÿ?ÿ I've always downloaded the raw/rw5.?ÿ Importing and running those files in Carlson or C3D, you can easily edit all your setups, sideshots, codes, rod heights, etc.

I would use the group command (not pointgroup) to select to bad points and the align command to correct them.

If you need a vertical bump do this before importing the good points

I have found that far more people do that than deal with the raw data like you and I do.?ÿ So I'm dismayed, not amazed.?ÿ The advantages are obvious. I like to say that if the raw data is correct it takes only a few minutes to review and run it.?ÿ If it isn't it is worth whatever time it takes to fix.

And how is it possible to run an adjustment without all of your observations that are in the Raw File??ÿ

And how is it possible to run an adjustment without all of your observations that are in the Raw File?

Some data collectors have functions to adjust traverses before outputting coordinates, but that is going to be a really challenging way to go about it. I sincerely doubt that such functions get used much.?ÿ Otherwise, it is not possible to make adjustments without raw observation data. Therefore we may assume that those who use coordinates exported directly from the dc are not adjusting, nor even really reviewing, their data.?ÿ ?ÿ ?ÿ

Got to be honest, when I first read " Is there a Civ 3D tool that correct occupation errors" my initial thought was a tool that would bring occupation into agreement with record boundaries.?ÿ Now that would finally be an upgrade worth paying for.?ÿ?ÿ
