[mapguide-users] Tool tips and Labeling

[Jason Birch]

There is no direct routing (or geocoding) capability in MapGuide.  However you could implement this at the database level.  Here's a link that might help:

I'm not sure if this will work with the OGR provider for PostGIS.  
 
I guess you could set up a table that contains a cross product of all the nodes, along with the routes between them and the relative costs.  This could get very, very large though.  
 
Also, you'd have to build some logic to extract the portions of the lines between the start/destination points on the line and the nodes at the start/end of the shortest route.
 
You'd probably want to use a few different weighting mechanisms too:  distance, speed, fewest left turns, etc.
 
This feature isn't of huge use to me, but I think it should be high on the wishlist.
 
Jason
