An anonymous reader writes: Two of the biggest drone manufacturers, DJI and 3D Robotics, are adding geofencing systems to their products to keep them out of restricted airspace. DJI's Geospatial Environment Online will be available on current versions of the Phantom, Inspire and Matrice drones, providing updated data on restricted flight zones due to regulation or safety concerns, including forest fires, major stadium events, VIP travel and other circumstances. GEO will also include restrictions around areas such as prisons, power plants and more. GEO, by default, will not allow DJI drones to fly in restricted areas. However, DJI is allowing its users to "temporarily unlock or self-authorize" flights in some locations. 3D Robotics will add the safety information software to its Solo smart drone app, containing basic information about federal guidelines (stay five miles from an airport, for example), national parks, airbases and more.
