Hello,
I was very pleased to see that the Living Atlas of the World hosts some data derived from SSURGO-level soils data for the U.S. I am curious, though, why the horizontal resolution is 30-m in the continental U.S. (CONUS)? It looks like the data was originally created in 2017, but updated in 2019 when the USDA released higher resolution (10m) gSSURGO data for the CONUS. Does anyone know why this is? Is it just a storage issue or is there an intention of updating these layers? In the data description, it says the data is 30m resolution in the CONUS and 10m elsewhere, which I believe is the reverse of what is available from USDA gSSURGO (see quoted text below from the Hydric Class dataset).
Thanks, Kristen

"This layer is derived from the 2019 version of the gSSURGO 30m (contiguous U.S.) and 10m rasters (all other regions) produced by the Natural Resources Conservation Service (NRCS). The value for hydric class is derived from the gSSURGO map unit aggregated attribute table field Hydric Classification - Presence (hydclprs)."
