摘要：

为满足提高渭河流域管理工作水平的迫切需求,在依托北斗新建测站和整合渭河流域现有信息化资源的基础上,构建天-地-空一体化监控体系,实现北斗卫星、遥感和地面监测立体化数据的实时采集。通过建立渭河流域水资源监控数据中心,采用瓦片金字塔、海量数据缓存和3S集成等技术,并基于三维可视化组件二次开发,设计并开发渭河流域水资源监控系统。以渭河流域陕西段为研究区域开展实例应用,研究结果表明,该水资源监控系统在实现流域海量、多源、异构数据整合的基础上,能够为渭河流域管理提供信息服务、计算服务和决策服务。构建的三维GIS平台具有可视化效果好、操作简便、可扩展性较好等特点,可为流域管理部门提供辅助决策支持手段。

Abstract:

In order to meet the urgent need of improving the management level of the Weihe river basin under the current situation,on the basis of the new station of Beidou and the integration of existing information resources in the Weihe river basin,constructing the integrated ground-air-space monitoring system,is constructed real-time data acquisition of Beidou satellite,remote sensing and ground monitoring is realized by the establishment of water resources monitoring data center of Weihe river basin,water resources monitoring system is designed and developed in Weihe river basin based on development of 3D visualization component by using Tile Pyramid,massive data cache and 3S integration technology.The result of a case study of Shaanxi section of Weihe river basin shows that the water resources monitoring system can provide information service,calculation service and decision service for the management of Weihe river basin based on the integration of massive,multi-source and heterogeneous data.The constructed 3D GIS platform has the characteristics of good visualization effect,simple operation and good scalability,which can provide auxiliary decision support means for the river basin management department.

Key words: water resources monitoring, stereo monitoring, 3D visualization, Weihe river basin, Beidou satellite
