But map data and location service are very different things.

Hi Poutnik,
The map itself is different from the location, as you noted, but they are
interconnected because we are talking about the "OK MAPS" download
mechanism to obtain *offline* map data.

That offline map data may contain location data, such as the BSSID:location
pair for every access point that many (most?) Android phones (not mine!)
report to Google every minute of every day.

Hence, the location data is interrelated with the map data *if* Google
stores that location data *inside* the *offline* map data.

Nobody seems to know (and yet, nospam always alludes to being an omnipotent
genius but he can't tell you or he'd have to shoot you) if the
BSSID:location data is stored *inside* of the offline "OK MAPS" downloaded
map data.
