[OSM-dev] Rendering like google maps in Mapnik : Customising osm.xml

[Martin Koppenhoefer]

maybe you can also consider rendering woods and forests in lower zoom
tiles. They suddenly disappear when zooming out, but it would be quite
nice to have them also for overviews, as they help a lot to structure
the map.

A nice example realized in Mapnik (i think), can be found here:
