Paul just posted an example for this kind of query: http://postgis.refractions.net/pipermail/postgis-users/2009-August/024137.html
Hope this helps. -- Kevin Thilani wrote:
Hi, I’m developing a shortest path navigation application on GIS. I came across a problem when we need to find a shortest path from the location which is not exactly located on the road. In that case I need to find what is the nearest road (geom.) to that particular point 1st. Is there any available post GIS function to do that? If so can you kindly explain that using an example. Thanks and Best Regards, Thilani
