Geographic Information Systems (GIS) provide a platform for displaying and analyzing spatial data. GIS systems allow you to view multiple layers of data simultaneously. GIS is a powerful tool for visualization, spatial analysis, and mapping.
GIS Day provides an international forum for users of geographic information systems (GIS) technology to demonstrate real-world applications that are making a difference in our society.
The first formal GIS Day took place in 1999. Esri president and co-founder Jack Dangermond credits Ralph Nader with being the person who inspired the creation of GIS Day. He considered GIS Day a good initiative for people to learn about geography and the uses of GIS. He wanted GIS Day to be a grassroots effort and open to everyone to participate.
GIS Day is a global event. Organizations all over the world that use GIS, or are interested in GIS, participate by holding or sponsoring an event of their own. In 2005 more than 700 GIS Day events were held in 74 countries around the globe. GIS Day is held the third Wednesday of November each year, during Geography Awareness Week, a geographic literacy initiative sponsored by the National Geographic Society.
