This shall give you some ideads what all of this is all about.

We worked on www.osm.to during NASA's SpaceApps Challenge in 2021.

We created QR codes that can be seen from space and satellites can scan and directly get information where they are

Our QR-Codes are so called ground control points and give local, free and open-source information.

That helps to create maps and especially www.openstreetmaps.org , thus our short link name OSM

We would like to have QR codes everyone. So we suggest to start deploying them somewhere :)

It is meant as a fun event for your city.

It is meant for everybody to join, meet and spend a nice time together building them.

And it is meant to help your area to get better maps from satellites or even your own drone like www.opendronemap.org

Just go to the "find-team" tab in this spreadsheet. Put some data there that you feel comfortable to share and then see if there are others from your area.

Then organize a meeting to plan.

Have fun and build some nice GCPs :)

go to the "find-team" tab in this spreadsheet

You can do whatever you like and that is fun for everyone.

If you have a place on your rooftoop to have a painted QR-code there, awesome!

If you have a place in your garden for arranging some ceramics tiles and form a qr-code, super!

If you like to BBQ and make hungry people working in said garden less-hungry, do it

And there are even more things you could do together, like coding together (it's open source), or using your own drones and make photos of your new QR-codes and make maps with open-drone-maps.
