Abstract
A system and method of mapping a persistent feature change of image data at a geographic location includes selecting a plurality of satellite images from a geographic location on different dates, producing a plurality of two-date satellite change images from pairs of the satellite images, comparing the plurality of satellite change images, and detecting a persistent feature change of image data in the compared satellite change images.The system may be implemented by selecting a plurality of satellite images from a database from different dates. A change detection module measures a change between pairs of the satellite images to produce a plurality of two-date satellite change images. A change confirmation module compares the two-date satellite change images and to confirm a persistent feature change.
