Drones for GoodA team led by a researcher from the Institute of Oceanography, working in Hai Phong, used small civilian drones with multispectral cameras to monitor the Bang La mangrove forest in Do Son and coral reef areas around Bach Long Vi Island, according to Viet Nam News (24 July 2026). Flying at low altitude, the drones captured high-resolution images, and the team produced ecosystem maps at a 1:5,000 scale.
