Would like to emulate google maps' driving directions functionality but use pgRouting instead. google's data over the project area & scale is quite a bit off so we want to use our own transport network data in postGIS.

any hints?

thanks.

  • There are other routing services available on the web - are you interested in those or do you really want to spin your own? – TheSteve0 Aug 6 '10 at 4:21
  • roll our own. we're moving everything to postGIS & pgRouting works "well enough" for our first project area, just lacks directions. – coldfusionPaul Aug 6 '10 at 11:41

Check out the OpenGraphRouter project.

Stephen Woodbridge has created a demo demonstrating the driving directions.[Dead link]

There is a pretty good thread on the PostGIS-users list related to this.[Dead link]

For setting up pgrouting and visualising it with Udig [http://www.utdallas.edu/~ama054000/rt_tutorial.html][1] [Dead Link]

Make sure your using the right SRID, common ones: 4326 - WGS 84 Long Lat, 4269 - NAD 83 Long Lat, 3395 - WGS 84 World Mercator, 2163 - US National Atlas Equal Area

Here is a good example of pgrouting in action with Open Street Map (Cloudmade 'Web Lite') Data

route: http://www.ridethecity.com/nyc?rid=866162 (icon markers are draggable and re-calculates route)

I've never used pgrouting myself (should have, actually) but http://twitter.com/pgrouting seems to be a good source for latest information about the project and users.
