The 'Digital geologic map of the Wallace 1:100,000 quadrangle, Idaho' Open-File Report 99-390 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, wa100k.aat, that relates to the wa100k.con (contact look-up table), wa100k.str (structure look-up table), wa100k.lgu (linear geologic unit look-up table) and wa100k.ref (source reference look-up table) files; a rock unit polygon attribute table, wa100k.pat, that relates to the wa100k.ru (rock unit look-up table) and wa100k.ref (source reference look-up table) files; and a geologic map symbol point attribute table, wapnt.pat, that relates to the wapnt.sym (structural point data look-up tables) and wapnt.ref (source reference look-up table) files.
A detailed description of the items in the Wallace 100K GIS are given in the text of the Open-File Report 99-390 available in Adobe Acrobat PDF format at http://pubs.usgs.gov/of/1999/of99-390/OF99-390.PDF
