STORING CHANGE FEATURES DETECTED FROM HIGH-RESOLUTION, REMOTELY SENSED IMAGERY

摘要

A method, system, and medium are provided for identifying facilitating storage and retrieval of information associated with high-resolution, remotely sensed imagery. In one embodiment, a data structure includes information derived from change-detection information associated with remotely sensed imagery, which change-detection information is useable by the application program, and wherein the data structure includes a plurality of change indexes, each of which (1) indicates change in a given item from a first state to a second state and (2) is associated with a feature set that includes one or more of item-texture features and item-spectral features, wherein each of the change indexes is an entropy balanced statistical (EBS) k-d tree index that describes features associated with items within a geographic area that is reflected in the imagery, and wherein the features include one or more of the item-texture features and item-spectral features.
