在线灾情地图实时发布系统的设计与实现 The Design and Implementation of the Real-Time Release System of Online Disaster Map

实时准确的灾情信息是灾害管理部门救灾减灾的关键，完善的灾情信息发布展示是公众日常生活的实际需求。本文基于天地图平台提供的详细地理信息服务，设计并实现了基于空间位置服务的在线灾情地图实时发布系统，该系统实现了灾情的实时发布、空间定位、灾情标绘、信息查询以及统计分析等核心功能，其成功运行为自然灾害的应急处置提供了辅助支持工具，为公众及时了解灾情信息提供了良好的平台，同时拓宽了测绘成果服务的领域。 The real-time and accurate disaster information is the key to relieve and reduce disasters for the department of disaster management. And releasing the disaster information perfectly is necessary for the public in the daily life. Based on the Map World, which provides detailed geographical in-formation service platform, the paper designed and implemented the real-time release system of online disaster map. The system realized the release of disaster information, spatial orientation, disaster plot, information query, statistics and analysis and so on, and all of these are based on spatial location services. The operation of the system provides auxiliary support tools for the dis-posal of the disaster emergency. Not only does it provide a platform for the public, but also it broadens the field of surveying and mapping results service.
