Integration and sharing of multiple heterogeneous geographic information and data sources are important for spatial analysis and decision making. However, the sharing and exchange of the geographic information are difficult because of semantic and schema heterogeneity of geographic information in different data sources. This paper presents an intelligent information sharing method of heterogeneous...
A design method for integrated modeling and assessment DSS in Hydroinformatics based on ontology and domain modeling is given. Four levels of design are discussed. First, formal concept analysis is employed for domain ontology analysis and construction in Hydroinformatics. Second, OWL is used as representation language for domain ontology. In third level, metamodel method of domain model is combined...
Integrated modeling, planning and management for watershed are complex system problems. Information sharing of digital watershed is a key for integrated modeling, assessment, collaboration, planning and management. This research analyses the methods of information sharing, and presents intelligent information sharing technologies. Framework of watershed integrated modeling, planning and management...
