The proper thing to do is to set up on it, accept that it's correct until you check it and find that for some reason it has an issue.įor that check DO NOT use some external control system!!!!!!!!! 25' vertically to the control that's the CONTROL.
VERTICAL ADJUSTMENT TRIMBLE BUSINESS CENTER HOW TO
You were given a gift of existing GPS control and it's up to the surveyor to know how to use it. What they are doing is inserting the given coordinates into a state plane file set up as a projection in TBC. As Lee says why would you calibrate to state plane GPS control.

From what you describe the office guys are not calibrating. It's important to get the terminology correct. Why do so many Trimble users not know how to use a projection? Seems odd. When projection is on state plane coordinate, you use a predefined state plane projection. Why are you doing site calibration on a state coordinate project? Is this method of site calibration better than the traditional site calibration method of going to each point in the field and taking static measurements? If not, how can the in-house method be done better? (Assuming the vertical information we have is "correct".) When we go out to the field to stakeout these points we said calibration they are within 0.05 ft in horizontal but in vertical they might be off by 3 inches or 0.25 ft.

For example, if they have a control point list from the state in Excel format they just insert these points on the software and then they get the necessary Lat/Long for each of them until they tie State Plane coordinates to Lat/Long coordinates, without even going to the field. I'm working for a transportation construction company that does their "in-house' site calibrations using Trimble Business Center. Generally: The flatter the site - the more critical the vertical. If there are vertically critical elements, break out the level (or 1" TS) to verify the vertical.

If the planset control has vertical problems, so will you and you might not realize it until the concrete is curing. Calibrations/localizations can make you think things will drain when they won't - it all depends on the original control. I'm glad to see that you are doing checks to validate the input data - maybe being off 0.25' vertically is within the error budget for the kind of work being done. Option 2 - calibration/localization using control points and control values identified in the planset - control should bracket the work area - Check your residuals.

Option 1 - input the project coordinate system from defined parameters - put your base on control points identified in the planset (or use a VRS) and CHECK into other control listed on the planset. This is a business decision so if the company understands the risk and still wants to do it - good luck to them - save a few bucks but risk a layout that doesn't match the plan location (Hz and/or Vert). This could work out OK 9-1/2 times out of 10. If I'm understanding this correctly - it sounds like a good way to end up with a variety of problems - like a drainage feature that doesn't drain. no field component - It can't be made better. If you mean "in the office" when you say "in-house" e.g. Surv3251, post: 451287, member: 12451 wrote: Is this method of site calibration better than the traditional site calibration method of going to each point in the field and taking static measurements?
