Abstract: In view of disadvantages of poor interactive, slow response and low scalability in traditional WebGIS application, this paper proposes a rich Internet WebGIS framework based on Flex after studying Flex technology. It elaborates on the hierarchical structure, composition and reciprocity of this framework and gives implementation. After applied in a public information service system, it shows that this framework can effectively enhance user’s experience, improve operating efficiency and provide stronger technical support for the release of spatial information.

Key words: WebGIS, rich client technology, Flex technology, ArcGIS platform
