Region offline caching for UAV navigation

Hey, I am working on some nifty navigation projects for some of my experimental drones. I am trying to figure a way to download the wifi map for a specific area and cache it in an offline database that will then be used in conjunction with GPS GNSS and tower triangulation. What would be the best way to go about acquiring wifi mapping data for this application?
