1. One or more non-transitory computer-readable media having computer-useable instructions for performing a method of detecting change in a geographic area, the method comprising: receiving initial high-resolution remotely sensed imagery, hereinafter “initial imagery”, that includes images and metadata that describes the images; deriving modified imagery from the initial imagery, wherein the modified imagery stems from the initial imagery and reflects aspects of the initial imagery in a normalized form; storing the modified imagery, resulting in stored modified imagery; identifying overlapping imagery, which includes at least two comparison scenes, which include, (1) a target scene that includes a portion of the modified imagery that describes a certain geographic area, and (2) one or more reference scenes that are subsets of formerly stored imagery that each also describes the certain geographic area; storing the at least two comparison scenes; automatically detecting change between (a) at least one of the one or more reference scenes and (b) the target scene, thereby resulting in a plurality of sets of change-detection information, wherein each set of change-detection information in the plurality of sets is associated with the at least one of the one or more reference scenes and the target scene; and storing the plurality of sets of change-detection information such that they are available to satisfy a query seeking information related to one or more aspects of the change-detection information.
