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. Come join us next Friday, November 13, at the Texas-A&M University San Antonio.
