DescriptionAbstract: One week after Hurricane Andrew made landfall in Louisiana in August 1992, an airborne videography system, with a global positioning system (GPS) receiver, was used to assess timberland damage across a 1.7 million-ha (4.2 million-acre) study area. Ground observations were made to identify different intensities of timber damage and then cross-referenced with the aerial video using GPS coordinates. Flight lines were established at 160km (10-mile) intervals perpendicular to the storm's path. The nominal flight altitude of 600 m (2,000 feet) above ground level and a 550mm focal-length camera lens resulted in a ground swath averaging 92 m (300 feet) in width. Video frames were captured digitally from the 8-mm analog videocassette at 800-m (half-mile) intervals along each flight path. Each video frame was interpreted for timber damage and placed into one of four arbitrary categories of bole-volume damage. The video frame locations were grouped into relative damage-zone polygons in a geographic information system (GIS). The polygons were then used to retrieve forest inventory plot information by damage zone and to estimate volumes of damaged timber.
