@[email protected] Yes. We used Mozilla’s cell tower database as an initial seed to scrape essentially all of Apple’s cell tower data. We’ll be scraping all of their Wi-Fi AP data from around the world too. We can also add other sources of data but we don’t really need it beyond having a path forward if Apple ever goes through a multiple year process to phase out having a publicly available network location service. It would be hard for them to do that since their existing devices depend on it.
