Contents: Landsat Thematic Mapper (TM) data were used to characterize the extent and intensity of coastal forest damage resulting from Hurricane Hugo (September 22, 1989) at Hobcaw Barony, South Carolina, USA. Low altitude vertical color infrared aerial photography and field observations provided the ground truth data necessary for validation. Bands 4 (0.76 - 0.90 μm) and 7 (2.08 - 2.35 μm) and three unsupervised classification techniques were used for forest damage classification of an image immediately following Hurricane Hugo. Similarly, a ratio of bands 7/4 was used as an index for mapping wind and storm surge damage and for change detection. The three unsupervised classification methods and the change detection analysis were effective at identifying the extent of forest damage. Healthy and heavily damaged stands were identified most accurately. Classification of damage intensity, especially for intermediate levels of damage, was more difficult and was affected by soil characteristics and understory vegetation.
