  • 防汛可视化指挥平台“一张图”技术研究

    ​

             系统主要功能包括基础地图操作，如图形控制、对象选取、地图缩放、空间量算、动态图例、态势标会等功能;信息资源可视化应用，包括水系，水库，山洪灾害村，山洪易涝点，地质灾害点，汛期临时避险场所和安置点，重点企业等，每张图整合了一种本地业务数据进行地图空间表达，数据以专题图形式准确标绘在相应坐标点上，每个重点部位挂载了相关防汛数据，数据高度整合并结合空间数据的应用，为辅助指挥提供直观表达，可靠依据，责任人信息直达，充分体现了防汛指挥的“一张图”思想，使“一股绳”宗旨得意有效落实，构建了上下联动,统一行动，快速反应的防汛救灾体系;实时险情检测，物联网系统与GIS系统整合，实时调取点位视频图像，监测信息，设定阀值，关联告警，建立健全一套完整的快速反应防汛救灾体系。
