Abstract

Systems and methods associated with an open area map are disclosed. For example, one method comprises obtaining an image of a layout. The layout represents a real-world area in which a person moves about. A grid is applied on the image. The grid may include tiles that fill in a ground area of the image. A routable map is generated as a function of the grid. The routable map is configured to provide point-to-point routing within the layout.
