Minnesota Maps

Data Types

Map Data

SSURGO map data include soil survey area boundaries, soil boundaries, water boundaries, and conventional and special soil features.  Map data are collected in 7.5-minute or 3.75-minute quadrangle units and are available in modified Digital Line Graph (DLG-3) optional and Arc interchange map files.

Attribute Data

Attribute data contain both estimated and measured physical and chemical properties and soil interpretations for engineering, water management, recreation, agronomic, woodland, range and wildlife uses of the soil.  The data are distributed in ASCII format with DLG-3 map files and in Arc interchange format with Arc interchange map files.


A metadata testfile in ASCII format is distributed with each SSURGO data set.  This file describes the content, quality, condition, history, and other characteristics of the data.
