1. A method of generating an open area map, the method comprising: receiving an image of a layout corresponding to a real-world area in which a person moves about, the image being in a vector graphics format and including an image reference object; generating a reference region from the image of the layout, the reference region representative of the image reference object; and combining a grid with the reference region to generate a routable map, wherein the routable map is configured to be displayed on an end user device and configured to provide point-to-point routing as a function of the grid, and wherein the point-to-point routing in the generated routable map includes route calculation not dependent upon one or more path segments determined prior to the route calculation.
