Abstract

Systems and method of managing map data on electronic devices such as portable electronic devices include systems and methods of preloading map data, managing map data storage, sharing point of interest or pushpin data with other electronic devices, and displaying map data.

Claims

1. A method comprising:

receiving, from a wireless communication device, location information indicating a current map segment of a plurality of map segments forming a map displayed on the wireless communication device, the current map segment including a device location of the wireless communication device on the map; and

identifying pushpin data based on the current map segment, the pushpin data indicating a pushpin location on the map and meeting a criteria received from the wireless communication device; and

sending the pushpin data to the wireless communication device.

2. The method of claim 1, wherein the location information comprises a current map segment index identifying the current map segment.

3. The method of claim 1, wherein the pushpin data indicates a plurality of pushpin locations on the map.

4. A method comprising:

displaying a map on a wireless communication device, the map formed by a plurality of rectangular map segments;

sending, to a server, location information indicating a current map segment of the plurality of map segments, the current map segment including a device location of the wireless communication device on the map;

sending, to the server, criteria for identifying at least one pushpin location;

receiving, from the server, pushpin data indicating the at least one pushpin location on the map and meeting the criteria; and

displaying the at least one pushpin location on the map.

5. The method of claim 4, wherein the pushpin data indicates a plurality of pushpin locations, the method further comprising:

comparing geographical pushpin indexes to map segment identifiers of the map segments; and

displaying only pushpin locations on the map that have geographical pushpin indexes corresponding to the map segment identifiers.

6. The method of claim 5, further comprising:

calculating the geographical pushpin indexes from the pushpin data.

7. The method of claim 4, further comprising:

downloading a non-cached map segment including one or more of the at least one pushpin location.

8. A method comprising:

sending first pushpin data to a wireless communication device based on a criteria and a geographical region associated with the wireless communication device, the pushpin data representing a first location on a map displayed on the wireless communication device and formed by a plurality of map segments;

receiving, from the wireless communication device, updated location information indicating a current map segment of the plurality of map segments, the current map segment including a device location of the wireless communication device on the map; and

sending second pushpin data to the wireless communication device based on the criteria and the current map segment, the second pushpin data representing a second location on the map.

9. A method comprising:

displaying a map on a wireless communication device, the map formed by a plurality of rectangular map segments;

sending, to a server, criteria for identifying at least one pushpin location;

receiving, from the server, first pushpin data indicating a first pushpin location on the map and meeting the criteria;

indicating the first pushpin location on the map;

sending, to the server, updated location information indicating a current map segment of the plurality of map segments, the current map segment including a device location of the wireless communication device on the map;

receiving, from the server, second pushpin data indicating a second pushpin location on the map and meeting the criteria; and

indicating the second pushpin location on the map.
