The National Cooperative Soil Survey Lab Data Mart Point Dataset contains detailed information about soil properties from soil samples taken at various sites around the world, with a focus on the United States. The dataset includes data on soil profiles, horizons, and analyzed properties like bulk density and pH. This digital soil survey is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was compiled using maps, remote sensing, and other sources to create a comprehensive inventory of soils and related areas. The dataset links soil map units to attributes in a relational database, providing valuable information on the extent and properties of different soil components.
