[MapProxy] caching from a.tile.openstreetmap.org with mapproxy

[Christian Willmes]

Hi,

I'm playing around with caching the OSM tiles from
http://a.tile.openstreetmap.org localy using mapproxy.

Tiles are getting accessed with urls like this from the server:
http://a.tile.openstreetmap.org/10/531/343.png

I configured my source in MapProxy like this:

  osm_tiles:
    type: tile
    grid: GLOBAL_MERCATOR
    url: http://a.tile.openstreetmap.org/%(z)s/%(y)s/%(x)s.png

When I access the service through the MapProxy demo app, it logs the
following request:

127.0.0.1 - - [15/Mar/2011:15:13:26 +0200] "GET
/service?LAYERS=OSMTiles&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326&BBOX=-113.5546875,-56.6015625,97.3828125,84.0234375&WIDTH=600&HEIGHT=400

Ubuntu/10.10 (maverick) Firefox/3.6.15"

And I get this image (which is obviously not correct) back:

http://dl.dropbox.com/u/21802018/service.png

I guess this is somehow connected with the order of axis or with the
grid I use...

Does anybody managed to cache this osm tile format and can share the
configuration?

Thanks a lot!
Christian
