Zapata County Soil Map Update

By | February 17, 2009

I just received an email from the Natural Resources Conservation Service (NRCS) indicating that the soil survey data for Zapata County, Texas has been updated.  We do some environmental work in Zapata County, and the soils data is an important component in some of the GIS analyses there.  Zapata County is unique in that it is one of the few counties in the United States that never had a soil survey book created for it, and because of that, it is one of the last counties to have GIS-based soils data.  The update message I received went like this:
