Wayfinding allows users to find the shortest walking route between any 2 points on your map, and shows them the distance and estimated walking time. This is important for maps of things like festivals or carnivals, where there are fences and entrance gates and temporary buildings or other infrastructure, that means the normal walking routing Google maps would display is not valid for the duration of the event. It’s also useful for spaces like university campuses or memorial parks where Google’s walking/pedestrian routing isn’t detailed enough.
This can be fairly complex to set up correctly. You need to have a map of all the “walkable areas” of your site, then draw multiple point lines representing walking routes encompassing all of those walkable areas. There is a processing stage that adds points everywhere your route lines intersect, and another processing stage that pre calculates the shortest distance between every pair of points in your route lines. Then for every way-finding request, the nearest point in the routes to both your starting and destination location is found, then the pre-calculated shortest route is displayed.
Note: Ensure you have you map overlay alignment set as accurately as possible, the routes you draw over the overlay image need the overlay to be correctly aligned with latitude and longitude.
