Soil surveys are being completed and published on a continuing schedule. As time passes, the data in published
surveys become dated. The official information about the soils in a given area is available from the Soil Data Mart, which provides the most current data about the soils.
If spatial data are available, the Web Soil Survey also provides
access to the most current information. In the “Date” column, the word “current”
is used for those surveys having both tabular and spatial data in the Soil Data
Mart. “Archived PDF
online” refers to any surveys published as PDF files on the Web, including new surveys as well as
old ones dating back to
1899.
