GIS Day

GIS Day is an annual event celebrating geographic information systems (GIS) based technologies. The event first took place in 1999. It was initiated by spatial analytics software provider Esri. Esri president and co-founder Jack Dangermond credits Ralph Nader with being the person who inspired the creation of GIS Day. He considered the event a good initiative for people to learn about geography and the many uses of GIS. He wanted GIS Day to be a grassroots effort and open to everyone to participate.

Today, the event provides an international forum for users of GIS technology from across the GIS industry to demonstrate real-world applications that are making a difference in society. Originally the Canada Geographic Information System developed in the 1960s by Roger Tomlinson, it is now used worldwide.
