Claim:
A method comprising: transmitting, by an end user device to a remote device, an image of a layout representing a real-world area in which a pedestrian moves about, the image generated by an end user associated with the end user device; receiving, by the end user device, a routable open area map generated by the remote device, the routable open area map generated as a function of a grid applied on the image, the grid including a plurality of contiguous tiles and having a shape that corresponds to a pedestrian-accessible sub-area within the real-world area, the shape having a boundary that corresponds to barriers in the layout; and providing, by the end user device, the end user with point-to-point routing within the routable open area map, wherein providing point-to-point routing comprises generating a path via adjacent tiles within the routable open area map, the path being formed of any adjacent tiles of the plurality of contiguous tiles such that any area of the pedestrian-accessible sub-area within the real-world area can be routed to.
