The easiest use case I can see is as a way for people to record where things are in a new office building, e.g., the route to the bathroom or supply closet. Then you could share the routes, though the bathroom example might not be one people want to share. Alternatively the office manager could create and share indoor routes. This would also work well for an airport.
