Little test-bed ROS project of mine to process the maps returned by the implementation of gmapper in the turtlebot3 package (turtlebot3_slam).
Note that since this is entirely a testing project and very much a work-in-progress, it's very rough around the edges.
Project should be cloned to ~/catkin_ws/src
or wherever you keep your catkin projects.
# Bring up the world and mapping
