As-Staked Coordinates Missing in Trimble Access

  • 1.  As-Staked Coordinates Missing in Trimble Access

    Posted 11-16-2021 09:33
    I am not sure if anyone has run into this issue before but we have had it happen on a couple of jobs. We did some GNSS stakeout in Access using an R10 base and rover setup. Upon exporting our custom stakeout report, no cuts/fills or as-staked elevations were populated and whenever we export the points as a CSV file, the as-staked points are not included (even after specifying "all points" to be exported). When we look at the points in the point manager, all the as-staked points have "?" in place of the grid coordinates and when you import the Job file into Trimble Business Center, the import summary says "The as-staked point XXXXXX has no computed grid coordinates..." and if you open the properties of one of the as-staked points, it shows a grid coordinate but says "(calculated)" after it. Has anyone else had this issue of as-staked point coordinates not being generated in Access and know of a fix?

    Are you able to upload the job file here? You haven't deleted any points from the job like base points, etc? Other things to check are your Coordinate system, Datum transformation and Geoid Model.

    Talking with our crew chief, it looks like they initially staked out the points but then there was a design change and the location/grades for those points changed. Instead of calculating a new set of points with different point numbers, they kept the original numbers and reimported them into Access, overwriting the original points, and then re-staked them. It looks like the as-staked points from the first day are not able to be calculated because the stakeout coordinates were overwritten (at least that is my best guess). I think this explains my issue, and we don't need the as-staked coordinates from the first day anyway since thse stakes were removed.

    It's not a good idea to overwrite points that have already been staked. When you do stake out in Trimble Access, two records are created in the Job file. You will get a point record containing the observation and a Stakeout record with the as staked deltas. If you overwrite these points the point records will be flagged as deleted however the Stakeout records will not. In this case your field crew would have been better off just creating a new job to re-stake the points.
    This would explain what you are seeing in TBC however I'm not sure if it would cause the null coordinates. I'm still happy to look at the file if you don't mind posting it.

    I believe the issue was what James McWha mentioned above. It was an issue with overriding the points and then the stakeout report did not know how to calculate the coordinates due to there being two sets of coordinates (old point and new point) I believe.
