Abstract: This paper proposes an integration scheme, aiming at the diversification and differences of coordinate system and projection as well as strong platform-dependent in the Web application lead to the insufficient research problem of Web Geographic Information System(WebGIS) and Remote Sensing(RS) integration. It analyzes RS of image projection and retrieval mechanism, combines with calculating spatial data and transforming projection, constructs medium client model, and implements the integration of WebGIS and RS. The application result of water and rainfall information for monitoring and warning system demonstrates that this scheme has a greater stability and practicability.

Key words: Web Geographic Information System(WebGIS), Remote Sensing(RS) technology, medium client model

摘要： 针对Web应用中坐标系和投影的多样化和差异性、对平台依赖性强等导致网络地理信息系统技术(WebGIS)和遥感(RS)集成方面的研究不足问题，提出一种整合方案。该方案通过分析遥感影像投影和检索机制，结合空间数据计算和投影转换，构建中客户端模型，实现WebGIS和RS的整合。在水雨情监视预警系统的应用结果表明，该方案具有较大的稳定性和实用性。
