USDA Soil Survey Areas by State

usdasoil/list-survey-areas

Lists the USDA soil survey areas of one U.S. state or territory: the area symbol (for example TX299), the area name and when its survey data was last refreshed, ordered by symbol, up to 100 rows. The area symbol is the input of usdasoil/list-map-units. The first row of the answer names the columns; a state with no survey areas returns an empty object. USDA Natural Resources Conservation Service data, served by Eden Engine; not an official USDA product.
