VISIBLE-REGION PHOTOGRAPHIC REMOTE SENSING OF NEARSHORE WATERS

Tsuguo Sunamura, Kiyoshi Horikawa

Abstract


By use of a synchronized camera system, multiband black and white photographs and conventional color photographs were taken respectively with the purposes of testing filters available for shallow-water photographic bathymetry, and of checking the availability of low-cost process imagery for the study of coastal processes. Kodak Wratten filters 29, 58, and 90 were employed for the multiband photography. A Wratten 90 filter provided the best correlation between water depth and the photographic density. The low-cost imagery, obtained in a laboratory from the color photographs by applying ordinary filters without using any expensive image processing devices, proved to be useful.
