Soil data
You can download data from their Web Soil Survey page, at https://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm and then (in theory) view it in their desktop app (if you have MS Access) or using their ArcGIS extension.
- So far I cannot view the data in their data viewer.
- It's because the database is empty.
- To populate the database requires a copy of MS Access, which I don't have.
