Occupancy grid mapping using multiple drones

Firstly, I honestly appreciate how this forum is providing quick feedback, it helps in accelerating our learning process.

My request below:

Please may I request a dedicated topic for occupancy grid mapping using multiple UAVs. When i check in “Programming Drones with ROS”, I found that mapping with SLAM is provided but occupancy grid is not.
Secondly, it will be beneficial if you can show us how to use drones for magnetic survey, for example how to use specific location on a world map with magnetic filed data and magnetic anomaly, and how to use sensors like magnetometer for drones.

Thank you very much

Hello @smaaji,

Those are really interesting topics. We definitely would like to add more learning material dedicated to drones, since it is a growing market. So we are going to take your suggestions for future courses/videos/projects.
