Hi,

Still me,

How can I save the 2d occupancy grid map generated by rtabmap?Use the "map_server map_saver -f path:"?

And,how can use the 2d occupancy grid map generated by rtabmap in rtabmap to navigation?

 I tried the follow way, but can't work, I add the follow to my launch file

  <arg name="map_file" default="$(env TURTLEBOT_MAP_FILE)"/>
  <node name="map_server" pkg="map_server" type="map_server" args="$(find rtabmap_ros)/maps/test_map.yaml" />
the map was saved by map_server.

this can generate a 2d occupancy grid map too, but I don't kown how to save the map.
