Hey Tom,

Awesome stuff. Sounds like we are working on similar things (except I'm fully entrenched in the django world).

I'll comment more inline...

Hey guys & girls,

So I'm working on making a good interface to Mapnik (via WMS) from Drupal.

So by interface to you mean a graphical admin panel/ web-based configuration page?

Are you working on making the WMS parameters configurable or the styling/rendering of a given layer configurable, or both?

It has become sort of a priority to have Drupal be aware of the actual data involved on the server - so that the coordinates of surface features, etc., are located in the mapping stack (Mapnik, PostGIS) instead of Drupal's database and schemas.

Hmm, I don't quite follow this... Maybe you could say more about how you currently have drupal talking to mapnik?

So I'm considering setting up FeatureServer and a WFS interface to query those details, and I'm interested to see what other people have done in this area. Since WFS isn't provided by Mapnik, is there a standalone server that is commonly used by the community for this purpose? WFS seems like a great solution to the problem here (sidenote: not directly querying PostGIS since the mapping server != the drupal server in many cases).

Yes I've used FeatureServer and it is awesome. FeatureServer with a PostGIS datasource is a fantastic way to interact with you geodata in a restful way, allowing you to query and update data in postgis and therefore modify dynamically the layers that mapnik is rendering. As far as formal WFS services GeoServer is also a great tool.

However, I'm not sure exactly what problem you are trying to solve. Clearly having the drupal server hosted on different machine than the mapnik WMS will present some challenges in integration :)

I'd love to hear more about how these tools are currently working for you and what you specifically hope to gain in having them as a more integrated stack.

Thanks for any experiences or insight! I'm really interested in getting a good stack built and contributing back when I make some progress.
