1. A computer-implemented method of generating comprehensive maps for route guidance, the method comprising:
receiving, by a processor, a floorplan delineating walkable and non-walkable areas;
performing, by the processor, spatial analysis regarding the walkable areas to find a path graph for the walkable areas, the path graph comprises a plurality of segments defined by vertices, and the plurality of segments defining local-walkable paths; and
generating, by the processor, a set of global-walkable paths from the path graph, the generating comprising reducing a number of dead-end segments, and reducing a number of vertices.
