Abstract

The novel coronavirus (COVID-19) pandemic is a public health emergency of international concern that caused disaster consequences all over the world. To mitigate and manage the pandemic, geographical information systems (GIS)-based spatial analysis has been used in a key role. To this aim, many GIS-based maps are produced by many national and international institutions. However, the produced maps are prepared by conventional methods and the features in these maps representing by their areal size. This paper proposes the diffusion-based cartograms for visualization of the COVID-19 outbreak. In the study, daily country-level data of the first 150 days of the COVID-19 outbreak were obtained from WHO, and the spread and spatial patterns of the epidemic were presented according to the number of confirmed cases and deaths. As a result of the study, it was observed that the cartogram is a powerful visualization tool and superior to the classical methods.

摘要

新型冠状病毒 (COVID-19) 大流行是国际关注的突发公共卫生事件，在全世界造成灾难后果。为了减轻和管理这一流行病，基于地理信息系统 (GIS) 的空间分析已发挥了关键作用。为此，许多国家和国际机构制作了许多基于 GIS 的地图。然而，生成的地图是通过常规方法准备的，这些地图中的特征由它们的面积大小表示。本文提出了用于可视化 COVID-19 爆发的基于扩散的制图。在这项研究中，从世卫组织获得了 COVID-19 爆发前 150 天的每日国家级数据，并根据确诊病例和死亡人数呈现了该流行病的传播和空间格局。作为研究的结果，
