[OSM-talk] Weather overlay

[Peter Körner]

Has anyone ever made an whether-overlay for openstreetmap using the 
Google [1] or the Yahoo API [2]? I think this would be possible with mapnik:
  * load a planet.osm into some kind of db (or process it in-place with 
a sax-parser)
  * find the regions with ZIP, PLZ or whatever
  * fetch the whether-info for these regions
  * add the regions to a/the postgis-db
  * let a renderd render the overlay-tiles using a stylesheet that only 
displays those whether-regions
  * server them using openlayers as an overlay

May i'll try this but I wanted to share the idea.
