WIN-PST 3.1 Soils
WIN-PST 3.1 takes soils directly from the SSURGO soils database (SSURGO Version 2.1 format)
The SSURGO database is either found in Section II of the Field Office Guide or on the 'F:' or 'G:' drives (e.g., F:\geodata\soils). If your soils data is stored in Section II, you should not have problems connecting to the database. Security restrictions on the ".\geodata\soils\" folder may cause WIN-PST to not recognize SSURGO database correctly. If the data is stored within ".\geodata\soils\" it is advised that you make copies of the desired SSURGO database on your local drive (e.g., C:\Users\\Documents\WIN-PST Soils). Note: Some states have placed the SSURGO data in other places. Contact your state's soil, GIS, or ITS staff for the correct drive and folder.
Outside of NRCS:
Users can download the soils data from Web Soil Survey. The SSURGO database can be placed anywhere on your computer. Make sure that if you have a laptop, that you don’t put it on a remote shared drive that is not available when you are not connected to the LAN (Local Area Network.) For more detailed information on working with Web Soil Survey soils including populating the empty SSURGO template with soils data, see:
