Geographic Information Systems (GIS) Day is an annual holiday celebrated every year by GIS professionals and enthusiasts alike! Since 1999, Geography lovers have celebrated this Holiday to bring awareness to the constantly evolving technology which is GIS and foster a sense of community among its users. Sponsored by serval originations such as the National Geographic Society (NatGeo), Association of American Geographers (AAG), and Esri (Environmental Systems Research Institute), GIS Day is now celebrated in countless countries across the globe! GIS is used by every person every day! Your weather app that updates forecasts based on your current location, Google Maps, and Find My Friends all use the Global Positioning System (GPS), which is a GIS! On the county level, our GIS Analyst and GIS Technician are responsible for making sure that mailing addresses and property information, such as boundaries and pending permits, are accounted for and up to date. Additionally, they act as the liaison for the County of Orange and FiberLync to determine where fiber has already been run and where it will be run next. The GIS specialists also work closely with other members of the Information Technology Department, as well as members of Development Services, Fire and EMS, and the Office of Commerce.
