Jack Dangermond wishes the world a happy GIS Day 2020. Jack thanks all the event organizers and participants for joining in this 21st year celebration of GIS. GIS Day is an international forum for users of geographic information systems (GIS) technology to demonstrate real-world applications that are making a difference in our society. It is a chance to share and illuminate the incredible work that GIS professionals are doing around the world. GIS is being used this year, perhaps more than ever before — helping with COVID-19 response efforts, wildfires and storm response, making cities safer, looking at how to organize information to make better decisions in planning and resource allocation, and much more. GIS Day is a time for you to share your passion and inspire others to use GIS. We hope you will celebrate and learn with us!
