COVID-19 Geospatial Resources Site

May 28, 2020
Over the past few weeks, the GIS Division has been working on a redesign of our COVID-19 Geospatial Resources site.  As the site evolved in the past months and more maps, apps, and data were being added, the site was getting quite large which prompted a review and redesign of the entire site.  Additional topic pages were added and maps, apps, and data were moved to these pages to simplify navigation and make the site more mobile friendly.

GIS Day is a global event during which GIS (Geographic Information Systems) users work to expand the understanding of how GIS technology and geography make a difference in our lives. GIS, a computer-based tool used to map and analyze features and events, combines the power of a database with the visualization capabilities offered by maps. Hundreds of thousands of people in the world use GIS to solve problems in areas such as environmental protection, pollution, health care, land use, asset deployment and routing, natural resources, conservation, business efficiency, education and social inequities.
