[OpenLayers-Users] pgrouting using openlayers

[Robert Sanson]

What happens when your click point for a start or end is not directly on a node? Does pgrouting snap the start/end points to the nearest vertex on the nearest road?
 
Thanks,
 
Robert

Here is an example that I put together using mapserver for the maps, 
pgRouting and I use a small PHP program to handle the the Ajax requests 
to communicate between OpenLayers and pgRouting.
