Montana SSURGO Soils Data Download
Tabular data in the MS Access databases for all survey areas has been updated as of January 2019. To maintain proper relationships between the spatial and tabular data, it is important to download the new databases. Spatial data for all survey area boundaries has been updated, and spatial soil map unit data for 18 survey areas shown in the checklist has also been updated.

Table of 2019 survey area tabular and spatial data
When you select a soil survey for download from the map or dropdown menu, a zipfile with the Montana survey area number will be copied to the location you select on your computer. The soil map unit polygons are contained in the spatial folder and the Microsoft Access database named soildb_MT_2003.mdb has been populated with the tables that are also found as separate text files under the tabular folder. All SSURGO databases are in Microsoft Access 2002/2003 format. This will not prevent you from opening them in Access 2007 or Access 2010. If you get a security warning when you open a SSURGO template database you may need to change your Microsoft Access security settings.
The spatial folder contains ESRI shapefiles named soilmu_a (soil map units); soilsa_a (outline of the survey area); soilsf_l (line features) and soilsf_p (point features). The soilsf_t text file provides a description of the line and point feature attribute abbreviations. Detailed soil properties for the map unit polygons can be found in the database tables and linked to the spatial data via the MUKEY polygon attribute.
