| 摘 要： | 在5·12汶川大地震灾后重建工作中,针对"四川省44县地震地质灾害应急排查信息系统建设"项目的具体要求,结合工作实际,通过MapGIS软件对各县(市)图件中震后地质灾害点进行平面坐标到地理坐标的转换,将重新计算获取得到的地理坐标与地质灾害点的属性信息一一对应连接,从而便于系统数据库构建时灾害点数据的录入与管理.

| Abstract: | In the reconstruction after the 5·12 Wenchuan Earthquake,in order to meet the specific requirements of the project which is called "Construction of Emergency Investigation Information System for 44 Counties Earthquake Geological Hazard in Sichuan Province",the MapGIS software was used to transform the panel coordinates of the geological disasters in every county map to geographical coordinates.The geographical coordinates which were recalculated and the points’ attribute information of geological disasters were corresponding connected.The transformation was convenient for the input and management of all disasters’ information in the construction of the system database. |
