The 'Digital geologic map of the Sandpoint 1:250,000 quadrangle, Washington, Idaho, and Montana' Open-File Report 99-xxx text contains a detailed description of each attribute code and a reference to the associated map symbols on the map source materials. The GIS includes a geologic linework arc attribute table, sand250k.aat, that relates to the sand250k.con (contact look-up table), sand250k.str (structure look-up table), sand250k.lgu (linear geologic unit look-up table) and sand250k.sr1 and sand250k.sr2 (source reference look-up tables) files; a rock unit polygon attribute table, sand250k.pat, that relates to the sand250k.ru (rock unit look-up table) and the sand250k.sr1 and sand250k.sr2 (source reference look-up tables) files.
