This article presents a new open source extension to the Emergency Events Database (EM-DAT) that allows researchers, for the first time, to explore and make use of subnational, geocoded data on major disasters triggered by natural hazards. The Geocoded Disasters (GDIS) dataset provides spatial geometry in the form of GIS polygons and centroid latitude and longitude coordinates for each administrative entity listed as a disaster location in the EM-DAT database. In total, GDIS contains spatial information on 39,953 locations for 9,924 unique disasters occurring worldwide between 1960 and 2018. The dataset facilitates connecting the EM-DAT database to other geographic data sources on the subnational level to enable rigorous empirical analyses of disaster determinants and impacts.
本文提出了一个新的开放源代码扩展，即紧急事件数据库（EM-DAT），使研究人员首次能够探索和利用有关由自然灾害引发的重大灾害的国家级以下、地理编码数据。地理编码灾害（GDIS）数据集以 GIS 多边形的形式提供空间几何形状，以及 EM-DAT 数据库中列出的每个灾害地点的行政实体的质心纬度和经度坐标。GDIS 总共包含了 1960 年至 2018 年期间全球发生的 9924 起独特灾害的 39953 个地点的空间信息。该数据集有助于将 EM-DAT 数据库与国家级以下的其他地理数据源相连接，以便能够对灾害决定因素和影响进行严格的实证分析。
