[...] have also had a great week exploring mapfish and openlayers, as I discussed a couple of weeks ago. It’s been great fun (in an intellectually challenging sort of way) [...]

Hey Yann,

Welcome! (and welcome to people reading via the new aggregator).

Yes, I think we can scale up the web mapping by looking at things like mapnik, and tuning the servers (mod_deflate, for example), and the databases etc. Good fun…

Let me get my map back up first though!

Hello Jo,

I will try to learn more about renderers, to be fair I am quite interested in system architecture around medium to large web mapping websites… the interaction between the database, the renderer, the portal itself, the eventual caching systems, is something I find very interesting

BTW, it seems that chris finally got the planet working on blogs.thehumanjourney.net , so you are aggregated now!

Hi Chris,

I don’t know if such a thing exists on the openstreetmap site, certainly the data that I have seen from the wheregroup’s wms is styled very differently to other osm data that I’ve seen. It would be very handy though!

Are there any existing free stylesheets for OSM data e.g. in SLD format? I’ve just downloaded the UK OSM shapefile data from CloudMade (thanks for the tip, by the way), so a corresponding stylesheet would be handy. Or am I missing some obvious alternative approach?

Hi Thomas et al,

Thanks for this- in the end I found a nice example for openlayers implementing the openstreetmap (mapnik) tiled map service (or whatever TMS) stands for. For getting a map online, that will do me, but I love the mapnik rendering so will work on getting that set up for our own use.

Thanks for stopping by!

I am really excited about MapServer’s rfc49.

Until then you can find some hand holding for mapnik at:

http://code.google.com/p/mapnik-utils/

I’d first try to render at sample tile with nik2img.py.

Then one simple way to serve mapnik rendered tiles for the web is to use TileCache with type=mapnik and then just point TileCache at your mapnik xml mapfile.

An emerging and very cool option is to style your OSM data using the pre-processor called Cascadenik, also found at: http://code.google.com/p/mapnik-utils/

here’s mapserver rendering osm data: http://mapserverosm.s3.amazonaws.com/parisosm.html

(osm dump loaded into postgis with osm2pgsql)

mapfile available shortly, as it requires a few patches to mapserver, scheduled in rfc49.

cheers,
