1. An image change detecting system to detect a change in a collected geospatial image from a geospatial image sensor carried by an airborne platform, the image change detecting system comprising:
a database;
an image processor cooperating with said database for generating a reference geospatial image corresponding to the collected geospatial image;
an image enhancer for enhancing at least one of the reference geospatial image and the collected geospatial image based upon at least one environmental condition; and
a change detector cooperating with said image processor and said image enhancer for detecting a change between the collected geospatial image and the reference geospatial image with at least one thereof enhanced by said image enhancer based upon the at least one environmental condition.
