How to determine GCP

Just want to find out if anyone knows of any tools that can assist with giving desired GCP locations within a specified area that needs to be flown for survey purposes. I know that Trimble Bussines Centre can give aprox locations where GCP is needed within a survey area. Thank you in advance.

  • Bikram,

    I basically take the area in CAD, offset the outlines inwards by +/- 30m, I then try to identify 4 corners where GCP should go, and then lastly, one GCP in the middle. For every flight I'll have 5 (min) GCP. Where area have to be split in 2 or more flights, I'll have areas sharing GCP. Example, 2 areas will have 8 GCP's and 3 areas 11 GCP's.

    Hope it helps

  • Hi, I was also facing the same problem with GCP locations. I was curious whether you got any solution (tool) for getting desired GCP locations by now, and can you guide me (walkthrough) with Trimble Business Centre software for getting approx GCP locations. Thanks !
