[Google Maps API v3] Custom routes/roads/paths from Building to Building, through buildings HELP!

[d.gl...@hotmail.com]

Hey guys. I need to know, and as quickly as possible, if what I need
is achievable.

I need to be able to, using either V2 OR V3 (preferably 3), create
paths which ignore buildings in a sense.

I was trying to create even a kml file to draw out all of the paths
myself, and then find some way to turn them on/off as needed.

For example. The user wants to go from point A to point B. Between
these points is a number of buildings. The user physically CAN walk
through these buildings(it's a campus). I want to show them that on
the map.

This way you don't have to do a loop-de-loop around, say, a parking
lot, just to get to the other end of it.

If there is ANY way AT ALL to do this, I'd love to know.

An example of what I require can be found here: http://www.uottawa.ca/maps/


It's all pre-determined paths based on the two inputs from the user
into the dropdown menu. I can plainly see this. But I have no clue
if a) this can be done in v3, and b) how on earth they did it
themselves.

Assistance required, and greatly appreciated!

Hey d.glover,

It sounds like you're looking for 'walking directions' between two points, which is currently an available travel mode option in V3:
http://code.google.com/apis/maps/documentation/v3/reference.html#DirectionsTravelMode

In order words, you can use the DirectionsService object to retrieve a DirectionsResult object containing walking directions from point A to B.  You could then easily display this on a webpage, with a map, using the DirectionsRenderer object.

Have you explored this option?


Thanks,

Dann

they did it themselves by applying Dikjstra's algorithm to calculate
the shortest path in a network. See the javascript files:
RoutingAlgorithm.js for the algorithm and PATHS.js for the network,
which is comprised of vertices and paths. For more details see
http://en.wikipedia.org/wiki/Dijkstra's_algorithm
