Abstract:
Linear Regression is used as a tool to calculate relationship between digital number and insitu total suspended sediment concentration in assessing total total suspended sediment at Bangpakong River Mouth to Srichang Island. By using Terra-Modis data, band 1,2,3 and 4 acquired on January, Fegruary, March and April, the result showed that the red band (band 1; wavelength 620-670 nm) was highly significant relation to sampled suspended seciment collected in January February. The algorithm was calculated base on the Linear Regression method; TSS. Although, clear sky and normal concentration of phytoplankton had to be concerned, the study showed that MODIS data in regards to good regional and temporal coverage was useful in monitoring suspended sediment and environmental change.
