Is possible to download data of the polygons somehow? I think a property called "wktpolygon" is used to store this type data that I saw in the new interface.
simplified country polyons are now available in the download directory. We are still figuring out best format, optimal size and what will be free and what will be premium.
all polygons in highest possible resolution will be available as premium option.
Basically is a Ruby library. You pass as arguments the name of the divisions, the fcode (and some other optional stuff) and you get the polygon of the place and the polygons of the children places.
