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.

本文为紧急事件数据库（EM-DAT）提供了一个新的开源扩展，使研究人员首次能够探索和利用有关自然灾害引发的重大灾难的国家以下地理编码数据。地理编码灾难（GDIS）数据集为EM-DAT数据库中列为灾难地点的每个管理实体提供GIS多边形和质心纬度和经度坐标形式的空间几何。总体而言，GDIS包含1960年至2018年间在全球发生的9,924场独特灾难的39,953个位置的空间信息。该数据集有助于将EM-DAT数据库与次国家级的其他地理数据源相连接，从而能够对灾难因素和影响进行严格的经验分析。
