A new specialty map service, the Soil Survey Map (Soil_Survey_Map), was published recently on ArcGIS Online (services.arcgisonline.com, server.arcgisonline.com). This detailed map shows the
Soil Survey Geographic (SSURGO) by the United States Department of
Agriculture’s Natural Resources Conservation Service. This level of mapping is designed for use by
landowners, townships, and county natural resource planning and management.
user should be knowledgeable of soils data and their characteristics. Farmland class, hydrologic, drainage, and
irrigation data can also be queried on the largest scale soil data layer. The soil units are symbolized by Esri to show
the dominant condition order for the 12 soil orders according to Soil
Taxonomy. These orders include Alfisols,
Andisols, Aridisols, Entisols, Gelisols, Histosols, Inceptisols, Mollisols,
Oxisols, Spodosols, Ultisols, and Vertisols.
There are three
different scale-specific layers in the map service. The largest scale data is derived by SSURGO
as stated above. The mid scale data
layer shows the U.S. General Soil Map of general soil association units by the
United States Department of Agriculture’s Natural Resources Conservation
Service (USDA/NRCS). It was developed by
the National Cooperative Soil Survey and supersedes the State Soil Geographic
(STATSGO) dataset published in 1994. The
small scale data layer shows the Global Soil Regions map also by the United
States Department of Agriculture’s Natural Resources Conservation Service.
