Abstract :
Based on OGC Web Service (OWS) code, the article describes that a gross structure of Web-based Spatial Decision Support System (WebSDSS) is designed, and model service and data service are both encapsulated into Web Service program and registered through UDDI to form virtual model library and database respectively. Model service management system is used for searching for and managing model service; data service management system is used for searching for and managing data service; flow-type interface is used for building framework flow for decision process; and service workflow controlling technology is used for ensuring trouble-free operation of decision process to provide operating environment for sharing of network model and data. Based on WebSDSS requirements, technologies such as model standardization, data description of model cell, model releasing, model searching and calling, integration of model and disparate data and generation and operation of decision support flow are studied and a WebSDSS prototype system is developed so as to realize broad sharing and calling of model and data resources on network and support web-based spatial decision.
