Soil Survey Project Boundaries

Soil Survey (SL) Project Boundaries (STE_SOIL_PROJ_BOUNDARIES_SVW) contain boundaries (study areas) and attributes describing each SL project (project level metadata), and includes links to the locations of other data associated with the project (e.g., soil survey reports, polygon datasets, plotfiles, scanned maps, legends). This layer is derived from the STE_TEI_PROJECT_BOUNDARIES_SP layer by filtering on the PROJECT_TYPE attribute. Project types include: SOIL, TIMSOI, and SOILSW. SL Project Boundaries should be used in conjunction with Soil Name and Layer Files and Soil Survey Polygons which divide the landscape into units according to soil association, name, type, drainage, parent material, and texture. Soil datasets and resources can also be accessed through the Soil Mapping Data Packages or the interactive mapping application Soil Information Finder Tool. Current version: v12 (2026-06-22)
