Abstract The study was conducted within a PNW estuary to determine the utility of false-color infrared film versus natural (true) color-negative film for recognizing and quantifying submersed aquatic vegetation (SAV) growing on an intertidal flat. During the summer of 1997 aerial photographs were obtained of Yaquina Bay, or during a negative tidal event using both infrared and true color film (scale 1:7200). SAV distributions were delineated from digital orthorectified images derived from both film types, using a digital classification approach as well as a traditional photointerpretation approach. A field survey of 160 sites was conducted within one week of the aerial flights. The detection of SAV and bare substrate was compared among all methods using an accuracy assessment technique base don the ground survey data. Resultant accuracy assessment values were similar for both film types. However, the digital classification obtained for Yaquina Bay, Oregon, using the color infrared film was judged to be preferable to that obtained from the natural film.
