Image reacquisition
First Claim
1. A computer-implemented method comprising:
- receiving image data of a geographic location;
estimating a rate of change for the geographic location using a processor, wherein the rate of change identifies a frequency at which the geographic location is modified;
determining an importance value associated with the geographic location using the processor, wherein the importance value indicates an likelihood that the image data of the geographic location is current;
determining, using the processor, observation bandwidth for image providers at the geographic location based on the estimated rate of change and the determined importance value, wherein the observation bandwidth identifies a rate at which the image provider reacquires image data at the geographic location; and
allocating the determined observation bandwidth by;
grouping a plurality of geographic locations that have substantially the same estimated rate of change and substantially the same determined importance value;
accessing a plurality of image providers each image provider of the plurality of image providers associated with at least one geographic location; and
determining the same observation bandwidth for each image provider associated with geographic locations in the same group.

Abstract
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.

14. A computer-implemented method for reacquiring images, the method comprising:
receiving images of a plurality of geographic locations; for each geographic location of the plurality of geographic locations; (1) identifying a rate of change for the geographic location using a processor, wherein the rate of change identifies a frequency at which the location is modified; and (2) determining an importance value associated with the geographic location using the processor, wherein the importance value indicates a likelihood that the image data of the geographic location is current; grouping one or more sets of geographic locations of the plurality of geographic locations that have substantially the same identified rate of change and substantially the same determined importance value, wherein the one or more sets of geographic locations of the plurality of geographic location are grouped using the processor; allocating a same observation bandwidth to image providers associated with geographic locations in the same set, wherein the observation bandwidth is allocated using the processor; and reacquiring images using the image providers at a rate identified by the corresponding allocated observation bandwidth. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. Processor means for:
receiving image data; estimating a rate of change for a geographic location wherein the rate of change identifies a frequency at which the geographic location is modified; determining an importance value associated with the geographic location using the processor, wherein the importance value indicates the likelihood that the image data of the geographic location is current; and allocating, using the processor, observation bandwidth to an image provider at the geographic location based on the estimated rate of change and the determined importance value, wherein the observation bandwidth identifying a rate at which the image provider reacquires image data at the geographic location and the allocating the observation bandwidth is based upon; grouping a plurality of geographic locations that have substantially the same estimated rate of change and substantially the same determined importance value; and allocating the same observation bandwidth to image providers associated with geographic locations in the same group.
