COVID-19 WMS service and Map Component


This page describes the Genasys WMS services that have been created to provide free public access to Coronavirus spatial data. The system displays the number of Coronavirus cases across the world as a WMS service. Tha data is updated daily, shortly after midnight GMT.   You are free to integrate these services in your mapping system. Alternatively, you may also embed the map in your Web page via an html link. The map below is an example use of the data. Click on a circle to see the attribute data.



Map Component Insert

The html "ilink" tag is the recommended method of inserting the Coronavirus map in a Web page, as shown in the following example:
