Lian Pin Koh, an assistant professor of Applied Ecology and Conservation at ETH Zurich, took it upon himself to develop inexpensive drones that local conservation workers can use for mapping and monitoring land use change in Indonesia. The drone flies autonomously along a pre-programmed route via a Google Map interface. Koh only takes manual control of the drone when landing in small spaces to avoid obstacles. The model aeroplane can stay in the air for twenty-five minutes and cover an area of fifty hectares during a single flight.
