Development of assessment method for damage distribution of urban buildings in post-earthquake reconnaissance using Geographic Information System

根据西宫市提供的地震资料，利用地理信息系统（GIS）对1995年兵库县南部地震造成的城市建筑物地震灾害进行了综合分析。讨论了地质、建筑物建龄与建筑物损坏的关系，以及建筑物损坏评估结果的比较。移动的数据采集系统是为建筑物检测人员和/或研究人员开发的，他们希望在地震后的侦察中收集和更新建筑物损坏数据。GPS（全球定位系统）接收器为GIS（地理信息系统）功能提供位置和现场信息。该系统使操作员能够在对建筑物进行日常维护或检查时轻松导航到特征并更新GIS数据。

Based on the data supplying from Nishinomiya City, comprehensive analysis on the urban earthquake disaster to buildings caused by the 1995 Hyogoken-Nambu earthquake has been done, by suing GIS (Geographic Information System). There are discussed on relation among geology, building construction age and the damage, and on comparison of building damage assessment results. The mobile data acquisition system is developed for building inspectors and/or researchers, who want to collect and update building damage data in post-earthquake reconnaissance. GPS (Global Positioning System) receiver provides positions and field information for GIS (Geographic information System) functions. The system enables operators to easily navigate to features and to update GIS data when performing routine maintenance or inspections for buildings.
