You may be surprised to learn how much geography matters in our everyday lives. The ability to link maps digitally to information enables us to visualize and understand patterns and relationships around us. Geographic information systems, or GIS, provides this link.
GIS describes a wide variety of computer-aided tools and services that capture, store, check, and display information related to positions on Earth’s surface. You probably use GIS every day without realizing it. When you use a smartphone to get directions or to find the closest restaurant to your location, you're tapping into the power of GIS. Here at NOAA, GIS is used to map oil spill trajectories, plot the paths of historic hurricanes, view and analyze nautical charts, and understand trends in areas such as sea level change and coastal socioeconomics. Analysts and scientists also use GIS for land use planning, business applications, scientific research, and even as a tool to aid in our nation’s defense.

Each year, we celebrate GIS Day in November as part of Geography Awareness Week. GIS Day started in 1999 as an educational event for GIS users to showcase their projects that have real-world applications. Opening their doors to schools, businesses, and the public, GIS users and vendors demonstrate the benefits of GIS and how it makes a difference in our society. Today, GIS Day is recognized globally with events occurring in dozens of countries.
