A generic software framework analyzes data from broad coverage sweeps or general larger areas of interest. Change detection methods are used to extract subsets of directed swath areas that intersect areas of change. These areas are prioritized and allocated to targetable assets. This method is deployed in an automatic fashion, and has operated without human monitoring or intervention for sustained periods of time (months).
This work was done by Steve A. Chien, Daniel Q. Tran, and Joshua R. Doubleday of Caltech; and Thomas Doggett of Arizona State University for NASA’s Jet Propulsion Laboratory.
