1. A method for detecting changes in geospatial imagery, the method comprising: operating an imaging device to obtain two images of a single location; receiving, at a processor, the two images; normalizing, by the processor, a visible band and near infrared band of the two images; registering, by the processor, the two images; dividing, by the processor, corresponding pixels of the two images into a first group with slope and a second group without slope; comparing, by the processor, slope groupings to determine which corresponding pixels have a probability of change greater than a predetermined threshold; creating, by the processor, vector polygons, based on the comparing slope groupings, to indicate areas of change in the two images; and generating, and communicating to the processor, a display image of the areas of change in the two images.
