论文摘要
越来越需要关于历史灾难的精确位置信息，例如天气或地震引起的大规模伤亡事件，但现有的灾难数据集通常无法提供过去事件的地理坐标。在这里，我们描述了一种新工具，即紧急事件数据库（杂草）的牧马人，该工具将纬度和经度坐标与广泛使用的紧急事件数据库（EM-DAT）中的条目相关联。 Weed将EM-DAT的输入记录作为输入记录，并使用与GeOnames Web服务的R语言相关的城市，州和其他位置类型列表。进行错误处理，并赋予用户自定义地理编码中使用的逻辑的能力；该工具的开源性还允许用户更一般的自定义或扩展。该工具为研究人员提供了通过地球物理，水文和其他地理空间变量轻松准备EM-DAT数据进行分析的能力。
There is an increasing need for precise location information on historical disasters, such as mass casualty events caused by weather or earthquakes, but existing disaster datasets often do not provide geographic coordinates of past events. Here we describe a new tool, the Wrangler for the Emergency Events Database (WEED), that associates latitude and longitude coordinates with entries in the widely used Emergency Events Database (EM-DAT). WEED takes as input records from EM-DAT, and geocodes the list of cities, states, and other location types associated with a given disaster using the R language with the GeoNames web service. Error processing is performed, and users are given the ability to customize the logic used in geocoding; the open-source nature of the tool also allows more general customization or extension by users. This tool provides researchers the ability to easily prepare EM-DAT data for analysis with geophysical, hydrological, and other geospatial variables.
