So now that I'm figuring out the necessary bits to generate isochrones (or rather distance isolines) from OSM+pgRouting+GRASS, I'd like to put this on a little web app to allow users to specify an arbitrary start point and distance (and later select from several profiles). I'm not sure what's best/fastest, to just send a raster to be overlaid on the OSM basemap, or to send it as a vector. I've done very little with OpenLayers, so I'm wandering through the woods quite a bit here. I was thinking of copying from the pgRouting workshop (i.e. use PHP process clicks and to deliver data).
You can see an example map here: http://wiki.openstreetmap.org/wiki/Safe_Routes_to_School_Mapping_Toolkit#Technical_details Any pointers to similar implementations would be appreciated, either for inspiration or code reuse.
