Our planet server is an OpenStreetMap Rails Port install running on Mac OS X Leopard, with a PostgreSQL database. You can access it like any other OpenStreetMap api at http://cartagen.org/api/…
If you want to map a very large area, but don’t want to run your own Planet server, try Dynamic Loading - this means you can use our Planet server with your own projects.
This’ll be a bit disorganized until the Planet server is complete. Also see the OpenStreetMap wiki and Osmosis documentation for more documentation.
osmosis-0.31/bin/osmosis --read-xml-change file="/Volumes/Planet/20090516-20090517.osc.gz" --write-apidb-change populateCurrentTables=yes host="localhost" database="****" user="****" password="****" validateSchemaVersion=no
to import many, run this ruby command from the directory containing changesets. Edit the path the osmosis as needed.
Dir.entries('.').select{|f| f[-4..-1]=='.osc'}.each{|f| `osmosis-0.31/bin/osmosis --read-xml-change file="#{f}" --write-apidb-change populateCurrentTables=yes host="localhost" database="****" user="****" password="****" validateSchemaVersion=no`}
