November 20th is GIS Day (Geographic Information Systems)

GIS Day is a grassroots educational event that enables geographic information systems (GIS) users and vendors to open their doors to schools, businesses, and the general public to showcase real-world applications of GIS.

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. The first GIS Day occurred in 1999.

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.

Some participants can be quite creative; a group of GIS users from Austin, Texas created the following YouTube presentation for the 2007 GIS Day: G-I-Yes!
