【Abstract】 This paper presents a review of the integration of watershed hydrological model with Geographic Information System and Remote Sensing techniques. Four scenarios of integration are discussed with emphasis on their characteristics, applications as well as the problems. The frame concept of high-level common ontology is proposed as a future research direction for the objective of a full integration of hydrological simulation model in the environment of GIS.更多还原
