in a first instance, in response to determining that the task should be executed on the client device, execute a limited version of the task, and

in a second instance, in response to determining that the task should be executed on the network server, transmit a message to the network server to request that the task be executed thereon, wherein the network server executes a full version of the task.

10. The client device of claim 9 , further comprising a battery;

wherein the processing hardware is further configured to:

determine a current status of the battery, and

determine whether the task should be executed on the client device or on the network server further in view of the current status of the battery.

11. The client device of claim 9 , wherein to determine the current status of the communication link, the processing hardware is configured to determine current downlink bandwidth of the communication link.

12. The client device of claim 9 , wherein the processing hardware is further configured to:

identify a plurality of tasks related to generating geographic content to be executed on the client device or on the network server,

determine, based at least in part on the determined status of the communication link, (i) a first group of one or more the plurality of tasks to be executed on the client device, and (ii) a second group of one or more the plurality of tasks to be executed on the network server, and

execute the first group of tasks, and

transmit one or more messages to the network server to request that the second group of tasks be executed thereon.

13. The client device of claim 9 , wherein the processing hardware is further configured to:

cache map data corresponding to a category of map data, the category of map data at least one of:

(i) having a relatively high level of user interest as compared to other categories of map data, or

(ii) being frequently accessed by a user of the client device; and

determine, based on the caching of the map data, whether the task related to generating geographic content for display via the user interface should be executed on the client device or on the network server.

14. The client device of claim 13 , wherein the map data is first map data and the category of map data is a first category of map data, and wherein the processing hardware is further configured to:

cache second map data corresponding to a second category of map data,

the second category of map data having a lower level of user interest than the first category of map data, and

the second map data corresponding to a smaller geographic area than the first map data.

15. A communication system comprising:

a client device configured to execute tasks of a certain type, related to generating geographic content for display on the client device;

a network server coupled to the client device via a communication network, the network server configured to execute tasks of the certain type upon request;

software instructions executed on one or more processors in the client device and/or the network server, the software instructions configured to:
