hi, I'd like to point out that an area variable might be a useful addition to MapCSS.
We have some uses of this already, as this is calculated by osm2pgsql. The default OSM Mapnik stylesheet filters text labels (on lakes i think) based on this. Places with a lot of buildings traced from Bing imagery, and a need emerges to display houses and larger/public buildings at different zoom levels to avoid visual clutter and still keep landmark buildings. RichardF commented on the #osm IRC channel: worth writing a mail to the mapcss@ list. I think we'll ultimately need to define a set of special variables that can be tested in stylesheets, and maybe _area (or _footprint) could be one of them _______________________________________________ Mapcss mailing list [email protected] http://lists.openstreetmap.org/listinfo/mapcss
