[OSM-talk] Global Admin Boundary Extracts

2014-03-31 Thread James Conkling 
Hi all,

I've been trying to find the best way to extract global admin boundaries
for admin_level 2 - 4 (or more, depending on size).  Up until now, XAPI has
been my go-to, but that seems to tap out at anything more than 10 or 20
degrees square.

[moreover, and this might be due to a mistake on my part, not XAPI's, after
extracting and using osm2pgsql, the planet_osm_polygon table is often
incomplete, though planet_osm_line is complete.  Every time I experiment w/
semi-large (country-size) XAPI extracts, the results are slightly different]

Anyone have any pointers on how to get global extracts (extracts of large
areas, even if the resulting file is not itself large)?  Thanks for the
pointers.

Are you looking for all admin boundaries level 2-4 worldwide or just
country by country ?

FYI, if you take only France, admin_level 4 represents more than 4MB of
compressed data.

What do you want to get at the end exactly ?
OSM raw data to work on or geometries in a PostGIS database ?

You may try overpass-API, but due to the size of the result, it may just
giveup too.

Get the planet from planet.osm.org and filter it with Osmosis.

Cheers,
