NEW August 2015: MARIS, in August 2015, downloaded the official September 2014 release data for all Mississippi counties from the USDA NRCS web site Web Soil Survey. The Import template for Access 2003 was loaded and the data table muaggatt was joined with the map unit shapefile soilmu_a_ms
on the fields Symbol and MapSym. The shapefile was exported to form this shapefile to keep the joined attributes. All metadata from USDA was loaded (XML) and all files were zipped. This was done for each county.
