汶川抗震救灾的基础地理信息综合应急服务

Integrated Geographical Information Emergency Service for Wenchuan Earthquake

在5.12汶川特大地震抗震救灾中,国家测绘部门设计和组织实施了以数据成果服务、专用系统服务和专题制图服务为核心的基础地理信息综合应急服务。其是针对汶川震区地形特点和抗震救灾主体工作需求,快速整合和提供震区已有的基础测绘成果和最新遥感影像资料;快速搭建集震区海量数据集成管理为一体并具备3维影像浏览、对比分析等功能的专用地理信息系统,为灾情评估分析和重建规划研究提供地理空间数据集成展示和分析平台;应需地制作反映受灾范围、受灾程度、救灾响应、规划思路等的各类专题地图和地图集,有效地表达地震灾害的时空分布、重建规划布局等。

National Geomatics Center of China had implemented an integrated geographic information emergeney service to the rescue works, mitigation and reconstruction planning of the devastating Sichuan Wenehuan Earthquake. Huge number of existing topographic data and new imageries taken after the earthquake were provided to thousands of users from different sectors. Three ad-hoe GIS systems were developed respectively for the rescue operations, damage assessment and the re, construction planning of the Earthquake affected area. On demand thematic mapping was implemented and a numbers of thematie maps as well as two atlas were produced, This integrated geographic information emergency service had played a very important role in the rescue operations, mitigation and reconstruction planning of the devastating natural disaster.
