How can I keep a .osm file of a specific area (country) always up-to-date?

How can I have an always recent copy of the OSM data in a specific area?

It should be easy to set up (for example in a cron job)

data update linux

The area must be customizeable and I prefer to not download everytime all data again but only the changes there.

Or simply you can download it from http://downloads.cloudmade.com/ They update their data nearly every week!

That is not working for me because weekly is not enough and they I need only one city / country the do not have. I want to transfer only the changes.

(since this has bounced to the top of the help list again)

Cloudmade's downloads page currently says "Last maps update: 13 December 2011"

Open the file with JOSM and before modify anything activate the "update" menu (i used a french JOSM so i don't know the english name, but it must be "update data" from File menu). Wait. Then work and upload you modification.

Hope this help

Unfortunately, you can't run josm automatically via cron.

you might be able to do this with the RemoteControl plugin (https://wiki.openstreetmap.org/wiki/JOSM/Plugins/RemoteControl). leave JOSM running and periodically (via cron) give it commands to import / load data.

Osmosis can combine change files with an OSM file, resulting in a updated OSM file. It will contain all updates from the change file, so you have to filter it with a bounding box.

osmosis  --read-xml-change file="planetdiff-1-2.osc" \ 
--read-xml file="planet1.osm" --apply-change \ 
--bounding-box top=59.485 left=17.872 bottom=59.161 right=18.264 \ 
--write-xml file="planet2.osm"

Osmosis can only update entire planets, not extracts. The question talked about data for a specific area, which Osmosis can produce from an updated planet, but not apply diffs to directly.

according to http://www.mail-archive.com/osmosis-dev@openstreetmap.org/msg00272.html , osmosis is capable of applying (complete planet) diffs to extracts.

Yes, but you would still end up with data outside the original extent in the output file. You could do it in two steps: first have osmosis or osmupdate apply the change file, then clip the output again using the boundary polygon or bounding box for your desired area.
