| Abstract | This study uses remotely sensed data acquired by the LANDSAT satellite for monitoring water quality. The study area is the Songkhla lake situated at the southern end of Thailand. Concurrent LANDSAT imagery and water quality data were obtained for two dates. The imagery of 15 Nov'82 was analysed to yield a model to predict water quality. After correcting the image for noise, atmospheric haze and normalizing for sun angle differences; it was found that only turbidity and salinity of all the water quality variables bore strong correlations with reflectance values. Stepwise multiple linear regression analysis procedures to was used to obtain equations relating reflectance values to water quality parameters. The validity was checked using data of 22 sept'82. The combined data of the two dates was used to formulate an improved model. This model was utilized to map the turbidity and salinity distribution over the lake. |
