SSURGO data depicts soil features on or near the Earth's surface, collected as part of the National Cooperative Soil Survey. This digital soil survey is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey, digitized from maps or compiled onto a planimetric correct base. The data set consists of georeferenced digital map data and computerized attribute data in a 7.5 minute quadrangle format, linked to a relational database of soil properties.
Use Cases
- Model agricultural yield potential based on soil type and property attributes.
- Plan land-use and conservation strategies based on detailed soil inventory.
- Analyze soil suitability for construction or engineering projects based on georeferenced map units.
Strengths
- Data is field verified, representing a detailed inventory of soils.
- Mapping scale is approximately 1:24,000, providing high spatial detail.
- Soil map units are linked to a relational database (Map Unit Interpretations Record) containing component properties.
Limitations
- Last updated 1998-12-31 23:59:59.999000; freshness should be verified.
- Coverage is limited to portions of six Wyoming counties as of October 2000.
- Column-level documentation is absent; field semantics must be inferred after download.

- National Cooperative Soil Survey
- Collection Method
- Digitized from maps, compiled onto a planimetric correct base and digitized, or revised using remotely sensed information.
