Abstract—A methodology is proposed for estimating the optical attenuation and proportional depth variation of shallow inland water. The process is demonstrated with EO-1 Hyperion hyperspectral and IRS-P6 LISS-3 multispectral images of Kolkata city nearby area centered around 22o33′ N 88o26′ E. The attenuation coefficient of water was found to change with fine resolution of wavebands and in pres...
