[OSM-dev] WMS with mapnik

[Stephan Holl]

Dear list,

I have found a note bout not reinstall the WMS-server for OSM. I would
like to use it and therefor trying to set up a test-WMS-server with
ogcserver coming with mapnik.

I followed the advises closely on[1] but my services dies with the
following error (in apache-errorlog):
mod_fcgid: jonpy error: ArgumentError at Wed Jul  4 07:24:46 2007

This is my wms.py-script (with only one layer for now):
from mapnik.ogcserver.WMS import BaseWMSFactory
from mapnik import *

class WMSFactory(BaseWMSFactory):

        def __init__(self):
                BaseWMSFactory.__init__(self)
                sty = Style()

                rl = Rule()
                rl.symbols.append(PolygonSymbolizer(Color(248,216,136)))
                rl.symbols.append(LineSymbolizer(Color(0,0,0),1))
                sty.rules.append( rl )

                self.register_style('style1', sty)

                lyr = Layer('world', '+init=epsg:4326')
                lyr.datasource =
Shapefile(file='/opt/mapnik/data/world_boundaries/world_boundaries_m')
lyr.title = 'test' lyr.abstract = 'abstract'

                self.register_layer(lyr, 'style1')
                self.finalize()

Perhaps someone could give me a hint how to solve this. I know that I
could use OpenLayers to serve the tiles with TileCache, but I like to
use desktop-WMS-clients with OSM-data

Thanks for any pointers

Best
