In a way, yes. I am mostly playing with tradional GIS and our national data but the following link will send you all the osm_lines from a 10 km by 10 km bounding box. Data comes from the OSM Mapnik schema and all the tags attached to the lines are included. See elements like <tows:tags> "ref"=>"3071", "name"=>"Ritvalanraitti", "highway"=>"tertiary", "surface"=>"paved", "z_order"=>"4" </tows:tags> http://188.64.1.61/cgi-bin/tinyows?service=wfs&version=1.0.0&request=GetFeature&typename=lv:osm_line&BBOX=346700,6780800,356700,6790800 You do not need to download the whole Czech data if you just want to check a couple of streets. Ten by ten kilometers in my example seems to be from an area that does not have many highways but it should give you an idea. This query will send all the osm_lines from the centre of Helsinki. http://188.64.1.61/cgi-bin/tinyows?service=wfs&version=1.0.0&request=GetFeature&typename=lv:osm_line&BBOX=385000,6671000,386000,6672000 This hundred by hundred meter box should give almost immediate response. http://188.64.1.61/cgi-bin/tinyows?service=wfs&version=1.0.0&request=GetFeature&typename=lv:osm_line&BBOX=385000,6671000,385100,6671100 I am updating data only every now and then but the database could be updated with the "Minutely Mapnik" system and vectors would never be more than a couple of minutes old. XML is not so interesting to look at but this OpenLayers example shows just similar XML vector data on top of a raster map. Use the Delete Feature tool and you will believe that they are vectors and nothing that is burned into the raster image. http://openlayers.org/dev/examples/wfs-snap-split.html I do not want to advertise WFS over native OSM services, it just happens to be a service I know somethign about. My message is that there can be other, maybe more flexible ways for utilising OSM data than just those boring tiles. -Jukka Rahkonen- _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
