Abstract

Systems and methods corresponding to an open area map are disclosed. For example, one method includes receiving an image of a layout corresponding to a real-world area in which a person moves about. The image is in a vector graphics format. A reference region is determined using the image of the layout. A grid is combined with the reference region to generate a routable map. The routable map is configured to provide point-to-point routing within the layout.
