【Abstract】 The complexity and richness of spatial data models and geographic information systems(GISs) together with the popularity of WWW have led to an increasing number of heterogeneous and autonomous geo-referenced information sources that spread over the Internet.How to integrate and publish these geographic information to facilitate accessing,sharing,and interoperability is still a challenge to both the research community and the industry. In this paper,we propose a framework based on GML and SVG technologies for integrating and publishing distributed geographic information.GML is adopted as the common format for spatial information wrapping and mediation,and SVG is used as a web-map publishing format that can be processed and displayed in Web browser. A prototype is also implemented based on the proposed framework.更多还原
