Abstract

Methods and computer readable medium for collaborating on geographical maps between two or more computers are disclosed. In particular, sharing a geographical location on a map between two or more computers and co-navigating a map between two or more computers are disclosed. With respect to sharing a geographical location, the geographical location is retrieved to the first computer. The geographical location is added to the map being rendered at the first computer and is sent to a second computer. A map including the geographical location is rendered at the second computer. With respect to co-navigating, a map is displayed from a map perspective at the first computer. The map perspective is sent to the second computer. A map from the same map perspective being displayed at the first computer is rendered at the second computer.

Claims

1. A method of sharing geo-spatial information for a user on a map between a first computing device and a second computing device, the method comprising:

obtaining geographical location of the first computing device;

adding an object representing the user and the geographical location in a first map file having a plurality of layers, the first map file being rendered at the first computing device;

sending the object representing the user and the geographical location to the second computing device;

aggregating the object representing the user and the geographical location into a map file at the second computing device; and

rendering the map file including the object representing the user and the geographical location on a display of the second computing device.

2. The method of claim 1 wherein the first and second computing devices are cell phones wirelessly connected to a network, the method further comprising:

displaying, at substantially the same time, the object and the geographical location at the first and second cell phones.

3. The method of claim 2 wherein further additional cell phones are connected to the network.

4. The method of claim 1 wherein the step of obtaining the geographical location of the first computing device includes retrieving said geographical location utilizing a global positioning system (GPS).

5. The method of claim 1 wherein the step of obtaining the geographical location of the first computing device occurs before the second computing device connects to a network and the step of rendering occurs after the second computing device connects to the network.

6. The method of claim 1 wherein the step of adding further comprises selection of adding the geographical location of the first computing device from a drop down menu.

7. The method of claim 1 wherein a user of the first computing device is designated as a leader and a user of the second computing device is designated as a follower.

8. The method of claim 6 wherein the follower can be selectively removed from sharing leader related information.

9. The method of claim 6 wherein the first computing device is a mobile device and the method further comprises utilizing GPS tracking to track the location of the mobile device of the leader over time.

10. The method of claim 9 further comprising displaying a trail for the location of the computing device of the leader.

11. The method of claim 1 further comprising displaying text associated with the geographical location in a map item pane on the display of the second computing device.

12. The method of claim 1 wherein the step of obtaining comprises storing a text sent by a user of the first computing device indicating the user'"'"'s location.

13. The method of claim 1 wherein the step of obtaining comprises receiving a broadcast sent by a user of the first computer device indicating the user'"'"'s location.

14. The method of claim 13 further comprising rebroadcasting the user'"'"'s location to the second computer device.
