Geocoded Disasters (GDIS) Dataset

This dataset is a geocoded extension of a selection of natural disasters from the Centre for Research on the Epidemiology of Disasters' (CRED) Emergency Events Database (EM-DAT). The dataset encompasses 39,953 locations for 9,924 disasters that occurred worldwide in the years 1960 to 2018. All floods, storms (typhoons, monsoons etc.), earthquakes, landslides (wet and dry), droughts, volcanic activity and extreme temperatures that were recorded in EM-DAT during these 58 years are included in the dataset. Due to resource constraints and inherent challenges with ascribing precise geographical information to certain disasters, the authors decided to limit the geocoding to events occurring in this time period, and further exclude technological and biological disasters, as well as a limited number of smaller disaster types. The highest spatial resolution in the dataset corresponds to administrative level 3 (usually district/commune/village) in the Global Administrative Areas database (GADM, 2018). The vast majority of the locations are administrative level 1 (typically state/province/region).

本数据集是对灾害流行病学研究中心（Centre for Research on the Epidemiology of Disasters, CRED）应急事件数据库（Emergency Events Database, EM-DAT）所收录的部分自然灾害进行地理编码扩展后得到的数据集。该数据集包含1960年至2018年间全球范围内发生的9924起灾害对应的39953个位置信息。本数据集囊括了这58年间EM-DAT中记录的全部洪水、风暴（台风、季风等）、地震、滑坡（湿滑型与干燥型）、干旱、火山活动以及极端气温事件。受限于资源条件，且为部分灾害赋予精确地理信息存在固有难度，研究者将地理编码的覆盖范围限定在该时间段内的灾害事件，并进一步排除了技术灾害与生物灾害，同时剔除了少量小型灾害类型。本数据集的最高空间分辨率对应全球行政区域数据库（Global Administrative Areas, GADM, 2018）中的三级行政单元（通常为区县/公社/村落）。绝大多数记录的位置对应一级行政单元（一般为州/省/地区）。
