1. A method for identifying changes in synthetic aperture radar (SAR) imagery, the method comprising:
identifying one or more locations of detected change within a first set of SAR imagery of a scene having a first resolution;
accessing a second set of SAR imagery of the scene having a second resolution higher than the first resolution;
performing change detection within the second set of SAR imagery of the scene based on the identified one or more locations of detected change within the first set of SAR imagery of the scene; and
mapping one or more trends within locations of detected change within the second set of SAR imagery of the scene over time based on a time history of SAR imagery of the scene.
