CartoGraffiti is a collaborative painting web application, using the Earth surface as it's canvas.
Pick up a location from Google Maps and make your art, with brush tools, stencils and stickers.
Once drawn, It will stay there, composing a virtual art gallery that anyone can see and extend.
CartoGraffiti is aimed for the iPad, but will be available online during BETA stage.


There are no rules.
This is an open collaborative canvas.
A permanent autonomous zone.
Once something is published, it will stay there. Forever.
Try not to cover entire areas and cover the maps.
Use cartography as an ally. Play with it.
There's no erasing. Like a wall, the only way to erase it to paint over.
There will be no editing. So please be nice.
Each zoom level is a new layer, a new canvas. If you zoom in or out, you'll see a completely different drawing.


CartoGrafiti is in ALPHA stage.
It means that it is still in development and not finished yet.
Anyone is welcome to join the tests, but keep in mind that it may be unstable.
Drawings made during this stage may be deleted before the official release. Or not. So please don't get too attached to them.

The painting system is ONLINE!
