Storing change features detected from high-resolution, remotely sensed imagery

Abstract

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.

AI Technical Summary

Problems solved by technology

If a person were armed only with images that depicted the area at various states, the individual might not know where to even begin looking for the road.

This given area of land (not to exclude water) might be vast, such that an individual would not even know where to start looking.

Moreover, even if an individual did know where to look, the individual might only see the constructed road, which might not be relevant because the road might have been present for any number of years (assuming that the individual is interested in finding areas that have changed over time).

In many situations today, a great deal of remotely sensed imagery sits idle, unsearched, and unused because there is simply too much information to even start analyzing.
