Geographic visualization and spatial analysis of COVID-19 based on GIS

Wang, Y.

By using the spatial analysis function of ArcGIS and the statistical function of EXCEL, the cumulative confirmed cases, cumulative cured cases and cumulative death cases of new-type corona pneumonia from January 2020 to July 2020 were correlated with the vector map of China' s administrative region to obtain the spatial distribution of new-type corona pneumonia nationwide. The cumulative diagnosis, cure and death tolls of the new type of coronary pneumonia were represented by color classification, and the situation of the new type of coronary pneumonia nationwide was visualized. The analysis showed that the distribution of the new type of coronary pneumonia at this stage was clustered, mainly centered in Hubei Province, spreading to the surrounding Hunan Province, Henan Province, Jiangxi Province and Anhui Province, and the sudden occurrence of the new type of coronary pneumonia occurred in very few regions. © 2021 Institute of Physics Publishing.
