Topic to be subscribed to using laser_height_estimation
I would like to give a try using laser_height_estimation package to estimate height of my flying robot as could be found here. What topic should I subscribe to? I couldn't find it in its tutorial.
Thanks in advance.
EDIT:
I found there are 2 of them: /mav/height_to_base and /mav/height_to_footprint. Which one is more relevant and which are the datatypes of them?
