Patent ID: 8825387

Claim:
A method comprising: translating coordinates associated with an open area map into real-world coordinates; and positioning the open area map within a geographic map as a function of the real-world coordinates, the geographic map representing a real-world area around the open area map, wherein the open area map is stored on a non-transitory computer readable medium, wherein the open area map includes an image of a layout representing a floor plan including a pedestrian walkable area, wherein a grid is associated with the image of the layout representing the pedestrian walkable area, the grid including a plurality of contiguous tiles, wherein at least a portion of the grid is designated as navigable and associated with a navigable area in the layout representing the pedestrian walkable area, and wherein the open area map is displayed on a user interface of a device and configured to provide point-to-point routing within the navigable area as a function of the grid, the point-to-point routing including calculating a route formed of any adjacent tiles of the plurality of contiguous tiles such that any area of the grid designated as navigable can be routed to, wherein at least two of the plurality of contiguous tiles are connection tiles, each of which link to a different a road segment of the real-world area around the open area map and external to the open area map, and wherein the route includes the at least two connection tiles, the road segments, and the adjacent tiles of the plurality of contiguous tiles.
