Soil Data Set for U.S. GrasslandsEntry ID: USDA0011
Abstract: The "Soil Data Set for U.S. Grasslands" provides georeferenced
soil data for grassland regions of the United States. The data
were extracted from Soil Conservation Service STATSGO data and
further processed by Colorado State University. In addition to
the soil data from STATSGO, soil texture data in the form of
present sand, silt, and clay are included.
Collection Organization: Natural ... Resources Conservation
Service, National Cartographic Center; further processed by
Colorado State University.
Collection Methodology: Preliminary and final STATSGO data
were received for grassland region states. Missing codes were
identified and flagged; some of the information was sent to the
state field offices for correction. Edge-matching between
states was checked and maps were edited, if necessary. Data
tables relevant to the work were imported into the database
structure and were"attached" to the polygon features through the
use of relational database commands. Soil texture data in the
form of present sand, silt, and clay were calculated and stored.
