Happy GIS Day 2013 to everone in group!!
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.
I wish a happy GIS day to everyone.
