Here's a bit from DJI's press release that details how GEO works:

Geospatial Environment Online (GEO) will provide drone users with up-to-date guidance on locations where flight may be restricted by regulation or raise safety or security concerns. With this major upgrade to DJI's existing geofencing system, users will have access to live information about areas temporarily restricted from flight due to forest fires, major stadium events, VIP travel and other changing circumstances. The GEO system will also show restricted areas around locations like prisons, power plants and other sensitive areas where drone flight would raise non-aviation security concerns.


GEO not only gives users updated information on flight restrictions, but it actually restricts flight by not allowing drones to fly into or take of in locations where "drone operations raise non-aviation security concerns," such as prisons and power plants.

However, those with a verified DJI account will be able to self-authorize and temporarily unlock flight in some restricted locations, though places like Washington D.C., for example, will remain as locked no-fly zones. To get an account verified, DJI is requiring users to provide a credit card, debit card, or mobile phone number (they promise they won't charge you, or collect/store your info), so that if a drone is found in a restricted place, they'll be able to trace it back to its owner.

DJI has also released beta versions of the GEO mobile app for both Android and iOS devices. (You can learn how to get your hands on it here.) GEO will work with both the Phantom 3 and Inspire 1 drones, and you can download their respective firmware updates here.
