Editing the survey database

[SageRoot]

OK so I am trying to do this the right way. I have imported a fbk file and I only have 2 control points in the fbk file. How do I edit the observations to designate the other control points that we shot in the field as control points in the fbk file.

In this case, you can run analysis on the network - traverse or least
squares, and the other observed setups will then be adjusted control points.
I don't think that's what you are looking for though. if the other setups
were not collected as "control points" in other words, defined with a
northing and easting, then you'll have to add the NE statements to the FBK
and re-import. Syntax looks like this:

NE 3 5461351.377 248410.107 232.300000 "HCP"
NE 4 5461403.393 248321.028 231.814000 "HCP"
NE 5 5461457.193 248193.838 231.140000 "HCP"

This would make three control points with a description of HCP.

This is what I get when I look at the .fbk in notepad. This is the final line of repetition shot in the field. I use TDS Foresight DXM to convert the .job file to .fbk

FC1 VA 133 52.23320 366.413 84.34220 "3/4"IPRCE15287"

I hope that I am missing something obvious, all I need is to designate some other sideshots as control points in the database.

Thanks for the help

This is getting a little outside my are of expertise. I think there is a
way you can add a northing and easting to this point and get it to come in
as a control point. let me ask around and see if I can get a better answer
for you. In the meantime, if you list the point created from this
observation in the drawing, what's the N and E?

I have translated and rotated the job since I am not having any luck with the survey database, but that shouldn't change the individual lines in the .fbk

Northing 273787.7594
Easting 1993507.8470
Z 505.86

So it sounds like your saying that if the NEZ is called out in the .fbk C3D recognizes that point as a control point. That would explain why the first 2 points work since the were created with COGO functions in the data collector.

Sage

[anthony.governanti]

Yes, you are correct. Sorry if my replies didn't help you any, I guess I
never understood what you were trying to accomplish.

I can see how to edit an individual survey observation but how what about when you want to rotate the entire job to known bearing? How do you do this?

[Anonymous]

Also, I have read Anthony's blog on this, but what about when youhave several Control Points? I just need an easy way to rotate the entire survey job. Can it really be this hard?

[anthony.governanti]

Unfortunately, it takes a couple small steps to get it all rotated, if you
don't have a direction defined.

Essentially, you need to change the location of you control points, which in
turn, will update the rest of the survey. If you are rotating, you can use
AutoCAD commands to figure out what the new location of a control point
should be (turning an angle from CP 1 to move CP 2). Once you have the new
coordinates for the second control point, use the editors from the Survey
Toolspace to change the control point, and the survey will update
accordingly.

It seems that when the data is collected in the field there is a way to denote a point as a control point. I have talked to TDS and they don't have an answer for how this is done. Their foresight software will convert to .fbk, but nobody at the help desk knew much about the format.

Oh well, looks like I will just continue how I have been working.

OK, try this on for size. I have a topo survey with several setups. ONE of the setups was keyed in wrong in the field. The instrument was actually set on point 10, and backsighting point 9. But the operator keyed it in backwards, with the instrument point listed as point 9 and the backsight as point 10. All the remaining setups are correct. I can't find a way to change the backsight and setup points from inside C3D. Is it possible to do so, or is my only choice to edit the fieldbook file and re-import.

[anthony.governanti]

Without testing further, I'll say the quickest thing in this case is to
simply edit the FBK and reimport.

I certainly understand that problem. I found that you can DELETE the individual setup, then re-import a FBK of just the corrected setup. This seemed to work with simple topo, I am going to play around with having the same scenario occur during a traverse setup. I usually have my guys crank our traverse, first thing, then move into the topo. So this scenario could happen and AFFECT the rest of my traverse.

Hope this helps.

We have found that if you explode the survey points then undo, they will turn into editable AEC Points just like in LDD. Is it possible to export an AEC Point into the survey database? I understand the function od holding the survey points in an external database and locking them but there has to be a way to translate points on a random coord system into a known coord system other than changing the coords of the control points. This has created a nightmare for boundary resolution.

If I understand you correctly
>>Is it possible to export an AEC Point into the survey database?<<

Meaning you have exploded them and probably have moved them where you like, and now wish to re-import them into the survey database?

If so, absolutely....create a new point file type under the Format Manager and export them into a FBK file. Then import the field book and they will all populate as control points.

As to your last question or statement
>>I understand the function of holding the survey points in an external database and locking them but there has to be a way to translate points on a random coord system into a known coord system other than changing the coords of the control points. <<<

You can RESET the observation database and assign NEW coordinate values for the basis of your survey WITHOUT re-Importing the fieldbooks. Is that what you are after?

Let me know.....
Hope this helps....
