Context-based reverse geocoding

摘要

In general, in one aspect, a mobile device can perform reverse geocoding based on context, in addition to latitude and longitude coordinates. The reverse geocoding can be used to determine in which geofence among multiple geofences the mobile device is located. Thus, the mobile device can be associated with a street address, a postal code, a named land feature, or a commercial, cultural, or political entity associated with the geofence. The context can include a pattern of movement, as well as an accuracy of the latitude and longitude coordinates. Information in the context can be compared to selection criteria of the geofence. A geofence having selection criteria that match the context the best can be selected.

1. A method comprising:
receiving, by one or more computers, a current location of a mobile device and a context of the current location, the context comprising a pattern of movement of the mobile device; identifying, from a plurality of geofences, two or more geofences intersecting the current location; selecting a geofence from the two or more geofences using the context, wherein selecting the geofence comprises:
determining a fence size for each of the two or more geofences;calculating match scores measuring matches between the fence sizes and the pattern of movement of the mobile device; andselecting the geofence based on the match scores; and determining that the mobile device is located in a geofenced area enclosed by the selected geofence.
