[OSM-dev] Free OSM tag queries, WMS and WFS

[Mayeul Kauffmann]

Hi,
An alternate (yet very similar) wms solution is to use osm2postgresql,
qgis and qgis-server.
See here:
QGIS supports the WMS 1.3 specification. Additionally, it supports some
additional optional parameters and requests which allow filtering:
http://www.qgis.org/wiki/QGIS_Server_Tutorial#Extensions_to_WMS

It also ships with a user-friendly js wms webclient with search
capacity, which allows some kind of filtering as well. Here a screenshot
I've just uploaded based on OSM data:
