Making address book a source of latitude and longitude coordinates

摘要

A method for determining latitude and longitude coordinates for geographic addresses input into an address book on a mobile device is provided. For each geographic address received for storing in a contact record, latitude and longitude coordinates are automatically determined and associated with the geographic address in a database of contact records. In some embodiments, for each geographic address to be input, the method first searches existing contact records for the geographic address and if the latitude and longitude coordinates for the geographic address are in an existing contact record, the contact record for the contact is cross-referenced to the existing record for accessing the latitude and longitude coordinates.

主权项

1. A method, in a mobile device, the method comprising:
receiving a non-geocoded geographic address for storing in a contact record of a database of contact records on the mobile device; automatically and without user initiation determining latitude and longitude coordinates for the geographic address, wherein determining the latitude and longitude coordinates comprises requesting the longitude and latitude coordinates from a location server over a wireless network; and in the database, associating the latitude and longitude coordinates with the geographic address, wherein determining the latitude and longitude coordinates further comprises;
receiving a suggestion for corrections to the geographic address from the location server if the geographic address is not recognized as valid by the location server;receiving a merit value along with the suggestion for corrections, the merit value indicating a likelihood that the suggestion is accurate; andautomatically updating the geographic address based on the suggestion if the merit value indicates a certain accuracy.
