National Cooperative Soil Survey (NCSS) Laboratory Data, NCSS Lab Data Mart Point Dataset

Metadata Updated: February 4, 2018

This layer represents the National Cooperative Soil Survey laboratory data of soil properties for soil samples taken at sites or points on the Earth’s globe – mainly from the United States of America but includes many countries. Sites are identified by unique site identifiers, though a site may be revisited over time producing more than one data set per site. A particular site will have one or more pedons or soil profiles with one or more soil horizons defined. Each horizon may have one or more soil samples that have been analyzed at a National Cooperative Soil Survey laboratory to produce measured and calculated values of soil properties, such as bulk density, particle size distribution, and pH.

This dataset is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This dataset consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. The soil map units are linked to attributes in the National Soil Information System (NASIS) relational database, which gives the proportionate extent of the component soils and their properties.
