Hi GWS-66,
While the Apple 3D Maps does give you more control over the video, CoPilot still works in 2D locations. You will still be able to set keyframes in a 2D environment, but will need to launch in Camera Mode to give you full control over the pitch and yaw of your camera during flight.
Beside the 3D functionality, CoPilot makes it simple for the pilot to operate a drone. You can set autonomous paths and check for buildings and terrain before launch. You can be alerted when you attempt to set a path not within FAA guidelines, and you can check local weather before flying.
The focus of CoPilot is to allow you to focus on taking pictures of video, and not piloting. It gives you full creative control over what you're capturing, while CoPilot handles all of the piloting. Hope this answers your question.
