Even though we have received some rain recently, drought conditions in Indiana continue to expand in some areas. This is an interactive map published on ArcGIS.com. Use the zoom tool or click on a county to see more information and zoom into a county

Colors in the drought layer indicate the following:
Abnormally dry (Yellow)
Drought - Moderate (Tan)
Drought - Severe (Orange)
Drought - Extreme (Red)
Drought - Exceptional (Brown)


The drought data comes from http://droughtmonitor.unl.edu where the Indiana portion is clipped out and transferred to the Purdue University geoserver. This drought layer is a dynamic Web Map Service (WMS) that is updated weekly around 8 am on Thursday morning.

Below are three previous weekly Drought Maps from (7/12/2012 - 8/02/2012) to compare with the current Drought map above.

A Bing imagery and street layer is displayed as the base map. If you would like to use this WMS in your own GIS application here is the URL: http://c4e4.rcac.purdue.edu:8001/geoserver/drinet/wms?

For more detailed information on the drought information visit http://drinet.hubzero.org/INDrought. The Greenness maps in the middle of web page shows the deviation from average, or how much "less" green we currently are compared with normal years.

The 2012 history link indicates how the deviation for normal has progressed to less green than normal as the summer has progressed. http://drinet.hubzero.org/2012greennesshistory
