Wayfinding graph consitutes of nodes and edges that define the navigable aisles and floor transitions in the venue.
The wayfinding graph is used in the IA wayfinder to find the route from the user’s location to the desired destination.
The image below shows a floor with Wayfinding graph. Note that the graph has the following features:
- Links from outdoor to indoor
- Links between floor levels
Routing using the graph has the following characteristics :
- Requesting a route from any coordinate uses the closest edge point as a starting point (e.g. starting from outdoor)
- Shortest route is used
