USER NOTES:
The GSOILS data base provides general level information and was designed primarily for regional, multistate, river basin, state and mutli county resource planning, management, and monitoring. Using the soil attributes, this data base serves as an excellent source for determining erodible areas and developing erosion control practices; reviewing site development proposals and land use potential; making land use assessments and chemical fate assessments; and identifying potential wetlands and sand and gravel aquifer areas.
Using NCSS mapping standards, soil maps in the GSOILS data base are based on the detailed soil survey databases (SSURGO). SSURGO was made using field methods. Surveyors observe soils along delineation boundaries and determine map unit composition by field traverses and transects. Aerial photographs are interpreted and used as the field map base. Maps are made at scales ranging from 1:12,000 to 1:63,360. Typically scales are 1:15,840, 1:20,000, or 1:24,000. The maps, along with comprehensive descriptions, produce an attribute and spatial data base for NCSS publications. The STATSGO databases were recompiled at a scale of 1:250,000. The data contain both estimated and measured data on the physical and chemicalsoil properties and soil interpretations for engineering, water management,recreation, agronomic, woodland, range, and wildlife uses of the soil.
The attribute databases contain the complete dataset for the state of Florida.
The GSOILS databases contain up to 21 soil components per mapunit identifier, whereas the SSOILS databases contain up to 3 soil components per mapunit identifier.
GSOILS should not be used for natural resource management for a single county.

DATA LINEAGE SUMMARY:
Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO) soil survey maps. Where more detailed soil survey maps are not available, data on geology, topography, vegetation, and climate are assembled with Land Remote Sensing Satellite(LANDSAT) images. Soils of like areas are studied, and the probable classification and extent of the soils are determined.
Using the USGS 1:250,000-scale, 1- by 2-degree quadrangle series as a map base, the soil data are digitized by line segment (vector) method to comply with national guidelines and standards.
