Not sure of the underlying map system. If it was Google maps, I could zoom all the way in to the coverage area in my neighborhood. As I zoom in, countries would be identified, states, cities, and my house. This does two things: 1) let’s me see specific coverage in my area. I can see the MLAT triangulation area and try to recruit more folks to apply for a pi so collectively we get better MLAT 2) Allows FA to analyze very precisely where they lack coverage, determine nearby cities to actively solicit new ADSB’ers 3) identify areas where there is no coverage and no city. Then be creative in increasing better coverage map results (better antennas) in coverage areas surrounding dead zone areas.
