How to use GCP - help

Posted by ActionDrone on April 13, 2016 at 2:55am

Hi all,

until now I made 3D mapping and nadir photography without any ground control points.

Next week I'll have to map a terrain on a slope, and I would use ground control points to get precise results.

I'm using a DJI Phantom 3 Professional and Pix4D, I can fly between 15 metres up to 100 metres AGL. The area is about 500x150 metres.

How can I print and use GCP to get an accurate survey? Can I measure the distance between GCPs with a yardstick and then apply that distance in Pix4D?

Thanks in advance for anyone that will help me.

    Better hire a land surveyor to do that job.

      I rule out this solution. I must do it by myself.
