GIS Day

Wednesday, November 14th, 2018, is GIS Day around the world!

What is GIS?
A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. It 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.

Does the National Weather Service utilize GIS?
With ever greater usage of Geographic Information Systems by partners and customers, NOAA and the National Weather Service have continued to expand our GIS products and services to meet their needs. However, there are many people that may not even realize they are using National Weather Service GIS products on a daily basis. Any time you check radar, you are using GIS. Anytime you click on a map to get a forecast...GIS. Watches, warnings, advisories...you guessed it...GIS.

Where can I find more information about GIS products and services offered through NOAA and the NWS?
