Description :
High spatial and spectral resolution sensors such as Landsat Thematic mapper were usually used to estimate the suspended sediment concentrations in the coastal zones. When studying the suspended sediment concentration in Danshui River in Taiwan, SPOT image was used because of its higher spatial resolution and this river being not as wide enough as the coastal area. Composite of band1 and band2 was found the best combination to express the suspended sediment. And the relationship of river suspended sediment and its environmental background was analyzed by overlaying the map of suspended sediment, vegetation type and pollution resources.
