Imagine that there is an online course where you could learn how Drones/UAVs could be used to solve agricultural problems and contribute to the global food problem. What if you could make it yourself? We present the steps given in the design and development of the MOOC Drones for Agriculture: Prepare and Design your Drone (UAV) Mission. This MOOC is the first attempt to teach people about aerial remote sensing in agriculture. From the early stage idea to the making-of, this paper will drive you behind the scenes that made this MOOC.
