The 'Digital geologic map of Spokane County and vicinity, Washington and Idaho' Open-File Report 98-503 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, spokco.aat, that relates to the spokco.con (contact look-up table), spokco.str (structure look-up table), spokco.lgu (linear geologic unit look-up table) and spokco.ref (source reference look-up table) files; a rock unit polygon attribute table, spokco.pat, that relates to the spokco.ru (rock unit look-up table) and spokco.ref (source reference look-up table) files; and three geologic map symbol point attribute tables, spcopnt1.pat, spcopnt2.pat, and spcopnt3.pat, that relate to the *pnt*.sym (structural point data look-up tables) and *pnt*.ref (source reference look-up table) files for each of the 1:100,000 quadrangles used in the Spokane County digital compilation.
