    • Apparatuses, methods, systems and computer- readable media for determining a room entrance of a map are presented, which Embodiments may identify a point of interest (POI) on the map indicative of the room entrance. Embodiments may determine a first edge of the map close to the POI and representative of at least a first wall on the map, and may determine a second edge of the map close to the POI and representative of at least a second wall on the map. Embodiments may then perform a rank analysis of the first edge and second edge based on at least one characteristic of the first edge and one characteristic of the second edge, and may determine the hallway edge of the POI based at least in part on the rank analysis.
