Passive data plotPassive Data - a "panchromatic" digital image of the coast that is obtained simultaneously with the laser elevation measurements by the NASA Airborne Topographic Mapper. The passive data are geo-referenced in a mosaic that appears as a black and white 'strip' image of the coast. The post-Bonnie (September 1998) passive data are shown in a strip map roughly 700m wide.
