I'm currently analyzing my GNSS solution of the measurements at the @osm_to ground control points on the airfield at for .

Here I measured all 3 markers of the big 2x3m QR-Code plane. Not a perfect solution, but very well in the sub-centimeters accuracy.

(Only the marker in the middle (top left of the QR-Code) is our normal reference point. I have measured the other mostly for fun/testing)

We use QR-Codes to create GroundControlPoints for photogrammetry by @quintusquanten. events.ccc.de/camp/2019/wiki/P c3lt.de/camp2019/talk/B9KAHU/

Packed and on their way to .
Thanks to @DF1LU to take good care of delivery logistics of the GCPs. At camp,
will take over of deployment. Stay ready with your for . :)
See you soon! Have Fun!

Finally they're there! 15m² of groundcontrol points. Car & parking lot for scale. So we're ready for . Thx to @quintusquanten @CosmoGecko @DF1LU + other @krautspace to make our project possible! Want to map the camp, too? Join here events.ccc.de/camp/2019/wiki/P

Thank you, donators! Minimum ground control points for are go. Currently, we will print them on 1x1.5m banners. If you want the banners to be bigger and viewable from higher altitudes, you can still help us. Just contact us here. Let's with !

Finally, we can do tests! :) Our first qrcode groundcontrol point banner for the arrived. All together, let's see if we can do a w/ @OpenDroneMap & @openstreetmap . More banners'll follow! More infos here events.ccc.de/camp/2019/wiki/P. Join us by retweet! :)
