【摘要】 结合数字水科院地理信息系统的框架体系和功能设计,着重研究了系统中涉及的关键技术和系统框架结构,提出了以Flex技术和SuperMap iServer REST API构建富客户端的WebGIS应用框架。通过构建水科院园区地理信息管理平台,实现基础地理信息数据的存储和空间信息的查询、分析和共享,提供水科院园区资源数据的更新维护、查询统计、空间分析、专题图制作等功能,为管理部门提供快速、准确的信息资源服务,为合理管理配置园区内的资源提供可靠的依据。更多还原

【Abstract】 Combined with framework system and function design of digital IWHR geographic information sys-tem,the key technology and framework system are researched emphatically. The WebGIS applicaton frame-work based on rich client building with Flex technology and SuperMap iServer REST API is proposed. Thebasic geographic information data storage and spatial information query,analysis and sharing are implement-ed,and the platform of IWHR spatial information management is constructed. The system has the functionsof regional resources updating and maintenance,query and statistics,spatial analysis,thematic map mak-ing etc.,and provides rapid,accurate information resources for the management. The reliable foundation forthe management of rational resources allocation is provided.更多还原
