GIS Day

GIS Day is observed on the third Wednesday of November around the world. It’s hard to imagine how we would manage without geographic information systems—they literally help us get anywhere in the world! GIS makes life easier and more efficient; it’s truly an incredible technology.

History

GIS Day was founded in 1999 by Jack Dangermond, co-founder of the GIS company Esri. The goal of this holiday is to educate people about the significance of GIS processes and their influence on daily life. Many take GIS for granted, but just a few decades ago, such technology was unimaginable. In the past, traveling to a new city meant asking strangers for directions, but now, a smartphone does all the work.

The first GIS system was developed by Roger Tomlinson in 1962. At first, his work was not widely appreciated. Tomlinson later shared that no one recognized the importance of his project, so it felt like a lonely journey. Thanks to his perseverance, GIS now stands as a technological achievement worthy of applause.
