marking parameter costmap_2d

edit

Hi all,

I have a very brief question regarding the marking parameter in the observation_sources tag. To be more precise, let's suppose that I set marking: false for my laser_scan in the obstacle_layer, then my local costmap will be no longer updated with the laser readings, but what about the motion planner in move_base? Will move_base take into account those readings to plan locally or is it going to ignore them (so basically setting marking: false will be equivalent to remove the obstacle_layer)?

Thanks and regards, Federico
