The National Weather Service in Birmingham has developed this GIS data page in an effort to share meteorological geospatial information to the public and GIS analysts.  This page is intended to be a one stop shop portal for access to GIS information that has been published in the past, as well as the latest information.  Our goal is to offer meteorological data to the most savvy GIS analysts as well as folks just beginning to learn about GIS.  Therefore, we've tried our best to offer data in multiple geospatial formats.  ESRI Shapefiles are offered for GIS analysts and agencies looking to create their own maps in ArcGIS and perform spatial modeling and analysis. Interactive web maps are also available through the use of ArcGIS Online & the NOAA GeoPlatform for those that don't have GIS software installed on their PC, but would still like to view detailed GIS information from the convenience of their web browser or mobile device.

Have questions or comments about these data?  We'd love to hear from you!  Send your thoughts to our Webmaster and we will have our GIS Focal Point contact you directly.  The more comments and suggestions that we receive from our customers will help to improve GIS data across the entire National Weather Service.

What is a GIS?

A Geographic Information System (GIS) 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.
