Octomaps (.bt format) and Gazebo worlds


Where could I find small octomaps with obstacles in .bt format (like small_map.bt from the Drone Course Unit 4) and the gazebo worlds they were generated from?
I have been trying to generate an octomap using the Husky robot but, unfortunately, they were not accurate.

Any help would be appreciated. Thank you
