Abstract

Open area maps and related systems and methods are disclosed. For example, one method includes receiving an image of a layout corresponding to a real-world area in which a person walks about. A restriction associated to a passageway within the image is generated. The image is used to generate a routable map for point-to-point routing. Routing through or around the restriction is based on whether or not criteria for passing the restriction is met.
