NOAA’s National Ocean Service and National Geodetic Survey have acquired color aerial photography and hyperspectral imagery for the near shore waters of the eight Main Hawaiian Islands. The images are being used to create maps of the region’s marine resources including coral reefs and other important habitats for fisheries, tourism and aspects of the coastal economy. A primary product of this effort is a benthic habitat map in geographic information system (GIS) format produced by visual interpretation of the remotely sensed image data. These benthic habitat mapping products have been generated by manual delineation of habitats from color aerial photographs, AURORA hyperspectral and IKONOS multispectral satellite digital imagery. In all cases, benthic features have been classified using a hierarchical Coral Reef Habitat Classification Scheme. In this work, important similarities and differences between the types of imagery tested are identified. Scientifically sound statistical comparisons of the benthic habitat maps are presented and conclusions are drawn that can be integrated into long term coral reef mapping objectives.
