problem importing ssurgo soil data

[Matthew Scholz]

Hi,

I'm new here so please forgive any breach of protocol (I didn't see a readme). 

I'm learning how to use QSWAT using QGIS version 3.28.9 and QSWATPlus version 2.4.0. I'm creating HRUs from downloaded web soil survey data from USDA. To do so, I've been following this manual, but it is out of date: https://swat.tamu.edu/media/116594/us_soilsv3.pdf

Does anyone have a more up-to-date reference? Two passages are antiquated from the pdf linked above:

1. The file structure described here no longer exists: "Opening a zip archive shows there is a text (.txt) file with information about the map, a user guide, and another zip file. Extracting that generates a folder with the name gssurgo_g_tx (the last two characters indicating the state), which contains a text file explaining that gSSURGO has superseded SSURGO and a folder named (in our case) gSSURGO_TX.gdb. This folder is a geodatabase, and can be opened in QGIS. But, unfortunately, although the geodatabase contains a raster version of the data, QGIS cannot read it. We need to convert the data from vector format to raster."

2. The Saga tool described cannot be accessed as described: "We are now ready to convert to a grid. Use Processing -> Toolbox -> SAGA -> Raster creation tools -> Rasterize to open the Rasterize form."

Thank you

Matt
