SCARY Inexplicable Elevation Changes

Postby aquaticrobotic » Wed Oct 07, 2009 11:27 am

I've caught this on three or four different occasions now. I have my stakeout descriptors setup to show Point Number, Descriptor, and Cut / Fill. As you can see below in store point # 1716, I shot the hub at an elevation of 359.8639. The descriptor of this line shows a CUT 359.68. It appears that the 359.8639 got transposed to 359.68. All my design points have an elevation of 0.
I'm wondering how often this is actually occurring and if it could be happening with just normal topo shots?
This is scary and needs addressed.

For an issue such as this, please copy the comment and email it to us directly so we can look into it at support@carlsonsw.com. Also, instead of pasting all of the point info into the email, please attach your .crd file or a text file. Thank you.

So, did you guys figure out what the problem was?
Is is a software glitch?

Thanks for letting me know that you have received the email.

Has anyone come up with an explanation as to what may have occurred?

Thanks so much for your attention to this matter and your excellent customer service!

I have had a response from Tech Support about this matter. I realize that others in the community may be wondering about my issue so I'll post the correspondence that we've had thus far below.

It's via email so read from bottom to top or you may get confused :)

Thanks for your attention to this matter.

Just to give you a little more information, I'm using a Topcon Hiper Pro Base/Rover setup and an Juniper Allegro CX data collector with SurvCE 2.09 loaded.

Unfortunately I do not have the CRD file associated with this issue. I never keep CRD files, only RAW and exported TXT point files.

I'm still not sure I quite understand your explanation of the issue. I'm confused by "because maybe the instrument it is faster than the update of the description". Also confused by "user changes something in the edit box (even a character removed at the end, will stop the update)".

Could you please explain these this further?

Thanks, Carlson is the best IMO.

Hello,

To make sure that we could find an explanation we also need the CRD file:
HAYDN 10-5.crd.

The description at the bottom of the screen updates constantly:
1. It could be not in sync with the actual reading from the instrument:
- because maybe the instrument it is faster than the update of the description.
- the user changes something in the edit box (even a character removed at the end, will stop the update).

Sincerely yours,
Romica Alexandru

I received the email response below and thought I should post it here to keep the issue up to date.
Thanks again to Carlson's support staff for their rapid response and attention to this matter



Hello,

The description automatically updates at specific intervals: 500ms in the SurvCE case.

If any change happens in the edit box that holds the description happens, the "automatic update" stops until the store completes.

I understand that the CRD does not exist, I would have wanted to check the elevation stored in the CRD for the staked point.

I will submit the bug to the SurvCE driver team for further investigation. We will find the answer.

Thank you for your bug report,
Sincerely yours,
Romica Alexandru

It has occurred again :!:

I'm sending the CRD., Raw, and exported text file to you guys over at tech support.

You'll notice that stored point number 1710 has an elevation that differs from the CUT elevation in the description. All my design points are 0 elevation so the cut should reflect the stored elevation.

I'm using Topcon Hiper Pro base/rover setup (5hz Position Rate), Allegro cx running CE version 4.20 with 107576KB RAM-- it's fast.

Please respond to acollier1976@gmail.com

Thanks!

I have had the same issue while using "Elevation Difference" with my Leica 1205, Allegro MX and Surveyor+ GPS. I create TIN files in Civil Suite, make spot elevation checks in Civil Suite (all looks good versus data used to make TIN), go out in the field and get areas that check and areas that simply do not. Up to .5' in some places where the data should be giving nearly cut/fills of 0'. Meaning these are places where actual data is being used (points, 3dpolylines, etc.)

I have consulted with tech support as well and have received the driver lag response as well.

Okay I love the products Carlson puts out BUT we as users and/or licensed professionals are putting faith into their products to give us the correct information. If I give a contractor a cut of 1' and it really is 0' or .5' for example, someone has to pay for the screw up and unfortunetly it's the licensed professional for grading the stake. This could be quite expensive over a large surface area. Not to mention the embarassment we face and the possibility of being fired or never used again. I AGREE, THIS IS A VERY SCARY SITUATION!!!!! If we are to gather data and solve solutions dynamically on the fly, then the driver lag time needs to be ZERO or as close as possible to! I'm not a programmer but do understand the behavior of what it should realistically do. If I am using a routine to find a elevation difference, then I should not be getting solutions from maybe the previous location. The robotic total station, for example, is constantly moving horizontally and vertically updating itself as we move around. The software HAS TO be able to respond at that same rate. If I'm not seeing this in a correct manner, please educate me and the other users that are having his problem. Luckly some of us are actually doing spot checks (quality control measures) out there. If you are a licensed professional, these results could have serious adverse affects on your professional status!!!!

In closing, I (as other users I'm sure) have spent a great deal of time, money and effort to incorporate certain products that pertain to our industry. I demand that this be seriously looked at!!!! We cannot afford to stake areas, bring up the data in the office, hand calculate and go mark grades to make ourselves "comfortable with the results". We should be able to rely on our software to do this.

Thanks,
Mark Driver
