[OSM-talk] Administrative boundaries export

2013-10-02 Thread César Martínez Izquierdo
Hi, I plan to create and make easily available a world-wide administrative layer based on OSM data, ideally including existing administrative codes (ISO, NUTS in Europe, etc) for each level and producing regular updates (for instance once a year). I think such a layer would be very useful for a n

The American Red Cross is dealing with this issue right now. We've built a database using GADM, GAUL, and Natural Earth. We initially wanted to rely heavily on OSM but because the relation breaks said it proved problematic. We've parked the use of OSM in our boundary dataset so that we can move fo
