Abstract
应急地理信息服务是以各种空间信息为基础，整合相关应急资源数据，对应急事件进行分析、判断、预测与危险性评价，进而成为整个应急指挥平台决策的“支撑平台”，是实现应急管理、应急决策和指挥以及空间规划的前提和基础。本文详细描述了应急地理信息服务平台功能流程，并以西藏自治区应急处置地理信息系统为例，介绍了GIS数据与应急资源数据的融合、应急标注技术的实现，应急空间分析模型的建设、二三维可视化系统互动等关键技术。 Emergency Geographic Information Services based on a variety of spatial information, integration of data related to emergency response resources, the analysis of emergency events, judgments, prediction and risk assessment, thus making the entire emergency command platform for the “support platform”, emergency management is to achieve , emergency decision-making and command and spatial planning on the premise and foundation. This paper describes in detail the geographic information service platform function emergency procedures, and emergency response to the Tibet Autonomous Region of geographic information systems, and introduced the Emergency GIS data resources with data integration technology to achieve marked emergency, emergency room model building, two three-dimensional interac- tive visualization system and other key technologies.
