Hi, Satoshi: The good thing I see is that it is really easy to get the file (no need of writing any query).
But it updates the files only once in a month, that can be a problem for people who want the updated OSM boundaries. Also, being only geojson is maybe not what many people want. Cheers, and have a nice week, Rafael. On 09/11/15 00:16, Satoshi IIDA wrote: > > Hello, > > What about Mapzen's boundary extract?
