i've got a soils data set that contains only abbreviated soil names and not a fuller description. Things like Qal, Qrb, Tuf, etc.

do we have a soils/geologic GIS/cartograher in attendance that knows of a good website to find out about what these abbreviations stand for? Surprisingly I can't find anything googlin' this....

The following two links might help you out. It sounds like you have SSURGO soils data and that you only have the main attribute table. You don't seem to have the join table you need for the abbreviation definitions. You might be able to download all that you need from the following website:

There is more information available here:

Hope this helps.

Here is another good link for NRCS's Soil Survey Geographic (SSURGO) Database.

Yes, if you are mapping soils in the US, please use SSURGO (not STATSGO). The attribute tables should be added to your layer using the mysid (?) field.

Review the metadata - especially the chart on attaching the correct look-up table. There is a field with a taxonomical description of the soil (i.e. Ventura loamy clay). This is a neat database, but be careful you read the metadata field descriptions carefully

Sound like a "geologic map" not a soils map, Qal, for example is "Q" Quaternary, which is an age, and the "al" is alluvial, which is a newer dirt fan which is usually found around streams. mostly sandy. go to the usgs site or here is a link for National Cooperative Geologic Mapping Program.

hope this helps.

was wondering if someone was going to pick up on that, and I didn't mention it b/c I have both the geology and the soils and needed the same type of info for both. the usgs site looks like one of the resources I was after. thanks.
