COVID-19 Information

Blue Marble Verified Coronavirus (COVID-19) Data Resources

As the world is shaken by the novel coronavirus (COVID-19) pandemic, here at Blue Marble we are looking to do our part to help promote reliable and verified data and information on the progression of this disease outbreak. As a GIS software development company we fully realize the need for reliable data and updated information on the current situation.

Below we have gathered a list of sources with maps and information on the status of confirmed COVID-19 cases. Some of the sources listed below contain worldwide data, while others focus on specific geographic areas.

Not all the below sources contain downloadable data, but the map produced and updated by the University of Virginia does have an option to download a CSV format table of data describing confirmed cases, deaths, and recovered cases for reporting countries worldwide. Johns Hopkins University and have made their data available for download through GitHub.


We have created an online map showing COVID-19 cases in Maine by county using data from the Maine CDC. This data is updated every day for the counties of Maine and in turn we update this map to communicate the information visually.

This map is hosted by MangoMap and the data was prepared in Global Mapper. We joined a table of data with a layer in Global Mapper depicting the counties of Maine. We then used the MangoMap extension in Global Mapper to produce the online map for sharing.


From our Italian reseller, Antonio Soriano, this map illustrates the cases of COVID-19 in Italy. The map combines data from known sources and contains layers showing the number of confirmed cases by province and region.
Also from Antonio Soriano is this map of the province of Avellino, Italy:
