Data, Maps & Tools

How to find your way through this section:

  • By topic: Click on a topic on the grid below to find maps, data and links to information about that category. Some links may appear in more than one topic, such as soil moisture, vegetation and agriculture. 
  • By interactivity: The “Tools” page links to interactive sites where you can customize information to meet your needs. The tools allow you to customize information by designating locations; date ranges; comparisons among events and conditions; and more. Many of these applications will create charts or maps specific to the situation you design. Interactive tools also appear under specific topics.

A selection of these data are available for download in GIS-ready formats from the Data Download and Services list.

The majority of the links show the continental U.S. For North American and Global data, go to the North American Drought Portal or the Global Drought Portal.
