ROS package to switch between occupancy grid maps. Based on the ideas proposed by multi_map_navigation, but slimmed down to focus only on switching individual occupancy grids, without the navigation or elevator components.
roslaunch map_switcher map_switcher.launch
Either of the following commands will switch the map
cd ~/catkin_ws
rosservice call /map_switcher/change_map elevator_1 map1
rosservice call /map_switcher/change_map elevator_1 map2
rosservice call /map_switcher/change_map elevator_1 map3
rosservice call /map_switcher/change_map elevator_1 map4
rosservice call /map_switcher/change_map elevator_1 map5
rosservice call /map_switcher/change_map elevator_1 map6
