【摘要】：长期以来,地球空间信息服务无法反映现场实况,不能满足综合监测实时信息服务需求。本文围绕空天地平台观测共享集成管理和时空信息高效服务问题,提出了传感网观测共享信息模型,重点阐述了基于对地观测传感网的最大时空覆盖优化布局、任务反馈控制、流式观测实时接入和动态仿真与预警决策支持的实时动态GIS关键技术,介绍了实时动态网络GIS平台GeoSensor及长江流域通航、防洪和发电时空信息感知管理应用。
[Abstract]:For a long time, geospatial information service can not reflect the actual situation, and can not meet the needs of real-time information service of integrated monitoring. This paper focuses on the integrated management of space-earth platform observation sharing and the efficient service of space-time information, puts forward the observation and sharing information model of sensor network, and focuses on the optimal layout of the maximum space-time coverage and task feedback control based on the earth observation sensor network. The key technologies of real-time dynamic GIS based on real-time access of flow observation, dynamic simulation and early warning decision support are introduced. The application of real-time dynamic network GIS platform GeoSensor and space-time information perception management of navigation, flood control and power generation in the Yangtze River basin is introduced.
