Hi,
I am regularly importing OSM data into PostGIS and use it both directly with OpenJUMP and through Geoserver WFS. I think it is great data for demonstrating WFS, especially queries. I haven't tried WMS because it would require some work to make SLD or Mapserver mapfile for styling. It would be nice to have such things available.
Updating the data does not take very long time because I can download either just a dump for Finland (http://download.geofabrik.de/osm/europe/) or Scandinavia (http://hypercube.telascience.org/planet/) but the size of the dump file is growing rapidly. Now it takes 10 or 30 minutes to import data into PostGIS with a laptop.
I do not know if OSM data in native format is used at the moment for making WMS. Mapnik (http://mapnik.org) seems to contain WMS 1.1.1 and 1.3 servers as well, but unfortunately Mapnik is almost undocumented. However, Mapnik is using PostGIS in between for rendering OSM tiles so I believe it is required by Mapnik WMS as well. Rendered OSM tiles are served by a variety of servers. Perhaps they could be cascaded somehow?

Hi,
looks like loads of people have interest in having osm data in their
geoserver applications... perhaps the osm project could also profit if
they had support for a WMS.

I believe that at one point there was interest in someone writing a
geotools driver (datastore) for .osm files directly... but the endeavour
faded out. Not sure why... if the reasons were technical, or just lack
of time/money.
So, could you give us an estimate of how much effort that would be?
Anyways, this would be a nice thing to have, and we could certainly
direct anyone interested in taking on the task.
but that would still mean, people having to update their osm snapshots
regularly (or else run the risk of having outdated data), right?
I'd be interested to know what you folks out there use osm for: mapping
(WMS) of raw data (WFS).
To the last question: does anyone have some code/technique to make the
osm maps be accessible through WMS?
Cheers,
Ugo

HI guys,
I like the open street map idea and I will like to find out the following:
1. how can open street map data be imported into geoserver ?
2. Which version of geoserver supports open street map ?
3. Is there a tutorial on how to use open street map and geoserver ?
Thanks,
Roman.
