Calling all surveyors, I need your opinion on something.

[jwilkerson]

I am a civil engineer (as well as the CAD guro at my company) and I have been having issues with our surveyors not get enough shots in the field. Specifically, when they shoot the top X and bottom X of ramp and driveway curb transitions, they only shoot the TC elevation and not the adjacent flowline and edge of gutter. This causes problems with crossing breaklines (especially around curves) when we go to build the DTM. I understand that these elevations can be found by interpolation but that requires a lot of post processing. I am just curious what the industry standard is on this issue.

Thanks,

Jeff

One idea that you might consider is to create a
paper map of a site and have the crew mark the shots they think they would need
to take in the field. Afterwards you can review it and point out what they
missed and what they could have skipped. It also helps to mark up a cross
section the same way. At least it gets them thinking about their
shots.

I'm in for the communication &
training!

when you have crews that have no cad skills
... you have to design your workflow in such a manner that they have to revise
their own work on the paper plan.  Make sure you have all measured
points & contours on.  Let them take photograps or make a
little movie on the terrain.  Take 10 miniutes and revise this plan
togheter with photo's and movie.  You'll learn both in a fast way. 
You'll be able to make a far better job description for them, they will
see where they have too little or to many points shot, and both will
learn from each others problems.

If you get no better results after some jobs
then sometingin else must be wrong I think ...

Good
point but I'm not confused and do understand there are more ways to look at
it but I do it the way I described. As mentioned my model and it matters to
me and it may not matter to the surveyors who Jeff speaks of but he
obviously thinks it matters or why complain? I think it's still lazy. Glad
to see a fellow surveyor make a comment though. Mark
