Johns Hopkins University, which developed the highly visited interactive map showing near real-time confirmed coronavirus (COVID-19) cases globally, has launched a new GIS dashboard that shows confirmed cases within the United States.
The interactive map, built using Esri’s ArcGIS Dashboard, is similar in setup to the global coronavirus map in that the main frame shows a choropleth map with side sections that list and graph the number of confirmed COVID-19 cases, deaths, and recoveries. The statistics and map of confirmed COVID-19 cases drill down to the county level for more granularity.
The statistics on the GIS dashboard can be filtered by selecting the state you are interested in from the drop down menu although the top counties by confirmed cases and deaths does not update to show only the selected state. The summary statistics can be furthered filtered by selecting a county for that state. The center map will zoom in to that county. Click on any county for summary statistics. A thumbnail COVID-19 status report for each county is also shown. Click on the thumbnail for the larger version of that COVID-19 status report which outlines healthcare and demographic statistics relating to that county’s coronavirus response.
The interactive map of coronavirus cases in the United States is not without some issues. For example, all confirmed COVID-19 cases for the New York City area seem to be lumped into coronavirus statistics for New York, New York (Manhattan). So the neighboring counties of Bronx, Queens, Richmond, and Kings are all showing erroneously as having zero cases.
It would also be helpful if there was at least a toggle option to see the confirmed coronavirus cases normalized against population so that the rate of confirmed cases is visualized. Areas with larger populations invariably will have a higher number of confirmed COVID-19 cases so creating a choropleth map of total cases instead of the per capita rate of cases is more reflective of a population map. A normalized map would allow users to see areas of the country where the rate of transmission is abnormally high or low.
