| Abstract: | Satellite image acquired from U. S. Landsat--5 The matic Mapper (TM) sensor in July 1991 for Wuxi, Jiangsu province was handled on computer with image processing technique and statistical approach. The in- formation extracted from remote sensing image clearly displayed the synopsis of water environment in Wuxi which was characterized as severe pollution. The spa- tial water quality distribution maps derived from image classification well correlated with surface water quality monitoring data. The result showed the great po- tential of satellite remote sensing in environmental mo- nitoring and water quality mapping. |
