For those of you who follow us on Twitter and/or LinkedIn, you might have seen us post an animated map showing current drought conditions across the United States each Thursday. Well now it is time to spill the beans on where I get these maps. Each Thursday, the U.S. Drought Monitor (USDM) publishes an updated drought map of the United States here. The USDM was established in 1999 as a joint effort between the National Oceanic and Atmospheric Administration (NOAA), the US Department of Agriculture (USDA) and the University of Nebraska, Lincoln. Included with the handy maps I post on LinkedIn/Twitter is a wealth of additional information, including:
This is an animation I put together weekly and post to our Twitter and LinkedIn accounts. It shows last week’s U.S. Drought Monitor map and then this week’s in a never ending loop.
- Statistics on the area in each type of drought zone,
- A drought change map,
- KMZs, shapefiles and a WMS of this drought data for GIS users,
- And even a tool to see if you qualify for agricultural drought relief.
Until my next edition of the Free For All, happy hunting for free geospatial goodies!
