Drone manufacturers will be able to embed the use of this system into their units to perform flightpath planning to avoid hazards. This would be a value-add of the drone (in that it can automatically avoid hazards).
Individuals and commercial users (such as delivery services) will be able to utilise the system to avoid loss or damage to their drone or its payload.
Commercial users will be able to program a flightpath for the drone, and ensure that an operator can focus on the observation capabilities of the drone, instead of the flight.
Privacy and no-fly concerns can be addressed as a benefit for non-flyers.
The data would be from a combination of crowd-sourced updates and submissions, paired with commercial agreements and observations of law, instantly accessed from other online repositories of relevant data.
