GIS Day is an annual event celebrating geographic information systems (GIS) based technologies. The event first took place in 1999.[1] 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.
