Abstract This paper describes the investigation of inning and silting in Hangzhou bay using 8 times TM/ETM+ since 1986. Remote sensing image processes including geometric correction and false color combination and mosaiking were carried out before deriving shorelines. Then the information of shoreline dynamic changes, inning and silting was obtained by utilizing the space analysis function of geographical information system (GIS). The results show that the shorelines of Hangzhou bay have been changing since 1986 mainly due to manual inning and beach breeding. The investigation also reveals that the manual projects are carried out on the basis of planning.
