A basic experiment for mappingof eelgrass distribution using the balloon with the simple spectralcamera in this researchwas conducted. The field survey stationwas selected to the Yoshina Tidal Flat in Takehara, Hiroshima Prefecture. Asa result, the followingmatters were clarified. 1) The characteristic for the spectral reflectance of the eelgrass appears in the wavelength at 450nm, 500nm, 650nm, and 700nm<. 2) A strongcorrelation was observedthe relationship betweenthe reflectance ratio (533nmand 440nm; 533nm and 620nm; 620nm and 720nm) and the area ratio (index of the density) . 3) The width of theobservation and the spatial resolutionof the balloonwereprovisionally calculated as 17m and 13mm. 4) Strengthof the balloon rope used was measured with about1000N. 5) The infrared composite color imageof the eelgrasstaken with the simple spectrum camera was clearer than the natural color composite image.
