Since 2003, the Geographic Information Science (GIS) professionals of San Antonio and surrounding areas have volunteered to host a GIS DAY event to encourage GIS users to open their doors to schools, businesses, and the general public to showcase real-world applications of this important technology. It is a way for GIS users to share their knowledge and passion with others and show the tremendous impact the technology is making in our lives each day.

What is GIS?

GIS stands for Geographic Information Science and is the science underlying geographic concepts, applications, and systems. A Geographic Information System integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.

Although you may not be aware of it, GIS touches our lives daily. It is used throughout the world to solve problems related to the environment, health care, land use, business efficiency, education, and public safety. The power supply directed to homes, the patrol cars and fire trucks that keep neighborhoods safe, and the delivery trucks on the road all function more efficiently because of GIS. This technology can also help businesses place ATMs and restaurants at more convenient locations, allow people to pull maps off the Internet, and help farmers grow more crops with less chemicals.


What is GIS Day?

GIS Day provides an international forum for users of geographic information science (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.
