The FAA allows pilots to fly drones for commercial operations if they obey part 107 rules. They also pilots who meet sufficient safety requirements to operate outside the normal regulations via a waiver.
I had been compiling information on the number of part 107 pilots, and thought it would be useful to find pilots with waivers nearby.
The FAA publishes that information in a poor format for searching, so I had the idea to make an interface to find pilots with a particular waiver, or near a particular location. It's a geospatial-enabled waiver search.
