SurvCE - Export Without Localization

Hello all.?ÿ Is there any way in Survce (5.09 if it matters) to export the coordinates of a GPS job without using the localization after it has been applied in the field?

Background info:

-crew went out with a localized txt file of points for the Control File (ie. 5000, 3000 points were created after the drafter drew up a legal plan and placed points at the corner to help the crew stake the points)

-the crew found 3 points and set them in the Topo File

-they created a localization with the 3 points in the Topo File, but one of the residuals was over 0.20m; however, they hit accept as they were just looking for bars (they figured even with the bad residual it would be "good enough" to get them in the area of the bar)

-all points now display the localized coord system in the Topo File (ie. 5000,3000)

-I want to export the Topo File points without the localization applied to a different coord system (ie. the standard NAD83UTM17 from the SurvCE Projection List)

?ÿ

I have done the following:

Equip->Localization->System->Set to CANADA/NAD83UTM zone 17N

Equip->Localization->Points->All points deleted

File->Points->Points displayed are still 5000,3000

?ÿ

When I was running the Leica 1200 GPS series, we would do something similar to this all the time.?ÿ We would pre-calc, find a few bars, one-step localize, and then export with a different coordinate system.?ÿ The Leica DC would store all the GPS shots "raw" and you could apply whatever transformation you wanted to export the points.?ÿ The points were always Lat/Long--you just got to choose how those were translated upon export.?ÿ Does SurvCE do the same thing?

Or is it more akin to the difference between the Leica 1100 and 1200 series total stations??ÿ On the 1100, once you punched in your scale factor it applied it to all the raw measurements.?ÿ Ie. 100.00m became 99.960m in the raw file.?ÿ On the 1200, the measurements were always stored without a scale factor in the dbx file; you just chose whatever scale factor was to be applied at export.?ÿ Measurements were still displayed scaled in the edit points screen; however, you could make a custom projection after the survey was done and export your measurements with that scale factor (ie. apply a scale factor of 0.999587 when the topo was completed, but use 0.9996 in the field).?ÿ The 1100 series was more "one and done."?ÿ Is SurvCE the same?

Any help greatly appreciated.

Side note--is this the method the majority of people using SurvCE employ for pre-calcs?

Within SurvCE, you can reprocess the raw data, both the conventional and the RTK. Generally, if you edit and save the localization, it asks you if you want to reprocess. but you can also do so manually...File Tab, Raw Data, Process GPS (I believe that is the order...). In that routine, you should be able to set the projection, the localization set, the geoid, etc.

I'm about to have to do this myself with SurvCE. What I do is go into the localization menu and turn off your horizontal and vertical control, let SurvCE reprocess the data to the raw data. If you have located something that you have a tight preferred coordinate value for, you can then add that point to the point file, with the correct coordinates, then add the new 'known' point into the localization, and re-localize. That usually works for me.

The key is that all of your GPS points have to have a lat/long associated with them in the raw file. Points collected with a robot might not adjust with the raw data reprocessing unless they somehow have lat/long associated with the point.

If points are collected using the DC, won't they also have lat/longs, regardless if they were GPS receiver collected or Robot collected??ÿ Don't use SurvCE, so I can't say if it does that, but I can't imagine it doesn't.

I use localize GNSS by points.?ÿ Can reprocess in SurvCE, in localisation delete existing localization point(s).?ÿ Use a new point with desired values and localise, or use/enter values from raw file .RW5.?ÿ Copy the RW5 file and change to .TXT to view, if you don't have Carlson Survey.?ÿ

Page 27

On the 5th screen, click on the 'Localization File' button, then click on the RED X (to remove the localization file). Continue reprocessing. You will be back to whatever projection / State Plane Zone you select.

I prefer to bring the entire job (all the files) onto my PC and then perform this operation in the PC Based emulator. That way I am not screwing up my field data in the Data Collector.

My PC based emulator is now strictly in Demo mode...grrr

@dmyhill

Use the SurvCE PC Emulator, not SurvPC.

 

These PC emulators work EXACTLY like the mobile version.

@dmyhill

This post, combined with Mark's excellent guide, worked.  Thanks for that.

This post is .......... awesome.  Thanks so much for that.

 

Side note: please check your ms@igage email tomorrow.  I would like to explore, potentially, purchasing some software from you.

Uh, where is the download link for the SurvCE PC Emulator?  I'm not seeing under the Carlson Software Downloads after I enter in my info.  That being said, I very likely need to get my prescription checked 🙂
