maybe you could skip the complete db and make a dynamic kml layer (by using a php file that outputs xml) in openlayers<br><br>Rob<br><br><div class="gmail_quote">2009/8/20 Peter Körner <span dir="ltr"><<a href="mailto:osm-lists@mazdermind.de">osm-lists@mazdermind.de</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Has anyone ever made an whether-overlay for openstreetmap using the<br>
Google [1] or the Yahoo API [2]? I think this would be possible with mapnik:<br>
* load a planet.osm into some kind of db (or process it in-place with<br>
a sax-parser)<br>
* find the regions with ZIP, PLZ or whatever<br>
* fetch the whether-info for these regions<br>
* add the regions to a/the postgis-db<br>
* let a renderd render the overlay-tiles using a stylesheet that only<br>
displays those whether-regions<br>
* server them using openlayers as an overlay<br>
<br>
May i'll try this but I wanted to share the idea.<br>
