c++ - Get geolocation source -


i using location api current location. according msdn, location source gps, wifi triangulation,ip, etc.

when location, how can tell location's source? if came form gps device or location based on availability of cell tower and/or wifi access points.

i saw in locationreport can get sensor id. can use id understand location came form?

i decided implement part in wy not accurate enough in case. use error radius tell if location came gps or based on availability of cell tower and/or wifi access points. of course bad gps can give me huge error radius, in case enough.
