Observation bandwidth is allocated to an image provider such that an image may be reacquired while optimizing the utility of the image provider's observations. The observation bandwidth is allocated with reference to the rate of change associated with a location where images are acquired by the image provider and to an importance value associated with the location. The rate of change identifies how frequently the location is subject to modifications. The importance value indicates a likelihood that users are concerned with receiving current image data at the location. Different locations having substantially the same rate of change and importance value are grouped together. The same observation bandwidth is allocated for the image providers at locations that are grouped together such that each image provider may reacquire images at the allocated observation bandwidth. |
