Developing and evaluating a method to disaggregate legacy SSURGO soil maps
… and curvature. For the United States soil map SSURGO, virtually all current soil map units have multiple soil types (known as "series") described within them, indicating there is great potential for such disaggregation. In this study SSURGO map units are disaggregated using descriptions of soil …

Assessment of SWAT to Enable Development of Watershed Management Plans for Agricultural Dominated Systems under Data-Poor Conditions
… Two sources of soil parameter values (SSURGO and STATSGO) were investigated, as well as three levels of DEM resolution (10, 30, and 90 m). Uncertainty increased as the input data became coarser for individual soil parameters. The combination of SSURGO and the 30 m DEM proved to …

An approach to map soil texture class on the Iowan Erosion Surface
… the NRCS Soil Survey Geographic Database (SSURGO). A set of 320 covariates were provided to Cubist, a machine learning algorithm, to make the data combination models. Twenty-seven rasters were developed to capture eolian sediment transport distribution across the study area. A detailed …

Improved Environmental Characterization to Support Natural Resource Decision Making: (1) Distributed Soil Characterization, and (2) Treatment of Legacy Nutrients
… change.The current method of soil mapping, SSURGO (USDA‐NRCS Soil survey), is often erroneous and misleading. Two studies in this dissertation are conducted to evaluate the potential that different resolution digital elevation models (DEMs) have to distribute soil characteristics …

Phenologic Assessment of Western South Dakota Rangelands
… cover data, 5) Soil Survey Geographic (SSURGO) range production values, and 6) State Soil Geographic (STATSGO) C3 percentage. Varying degrees of success were achieved in the six validation methods. Vegetation cover by Daubenmire frame provided a poor relationship with remotely sensed …

Creating A Stormwater Runoff Model For The City Of Oxford, Mississippi: When It Rains, Where Does That Water Go?
… data collected from rain gauges, soil data from ssurgo and published soil infiltration rates from a Lafayette County soil survey, impervious cover created from Lidar and Aerial Photography, published evapotranspiration rates, and storm drain locations provided by the city of oxford planning …

Development of Standard Geodatabase Model and its Applications for Municipal Water and Sewer Infrastructure
… available data from resources such as USGS, SSURGO etc. Field mapping files are generated from the source files and the standard data model. These are then programmed to the common Extensible markup Language (XML) file developed as a base which is then converted to the data model where the …

Incorporating Climate Sensitivity for Eastern United States Tree Species into the Forest Vegetation Simulator
… mapped in the USDA Soil Survey Geographic SSURGO database. Results showed climate was a stronger driver of site index than soils. When soils and climate were used together, site index predictions for species grouped as conifers or hardwoods were almost as precise as species-specific models …

Estimating site susceptibility to Scotch broom dominance in young Douglas-fir plantations for control prioritization in western Washington, USA
Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii), a keystone species in western Washington, faces threats on plantations across this region from the invasive species Scotch broom (Cytisus scoparius (L.) Link), whose invasions on recently established stands can lead to mortality of …

Environmental and Digital Data Analysis of the National Wetlands Inventory (NWI) Landscape Position Classification System
The National Wetlands Inventory (NWI) is the definitive source for wetland resources in the United States. The NWI production unit in Hadley, MA has begun to upgrade their digital map database, integrating descriptors for assessment of wetland functions. Updating is conducted manually and some …
