Geologic data from a generalized geologic map of the Coeur d'Alene mining district by Gott and Cathrall (1980) was entered into a geographic information system (GIS) as part of a larger effort to create a regional digital geology for the Pacific Northwest. The map area is located in northern Idaho and extends across the state border into western Montana.
Purpose:
To provide to the public a digital geologic map database of the Coeur d'Alene mining district.

Logical_Consistency_Report:
Plate 1 from Gott and Cathrall (1980) was the primary source of geologic data. Maps by Hobbs and others (1965) and Wallace and Hosternman (1956) were used to attribute the faults.

Process_Description:
The 1:62,500-scale paper geologic map (Gott and Cathrall, 1980, pl. 1) was digitized into PC ARC/INFO using four latitude and longitude pairs for registration points. All four registration points were visually transferred from the corresponding 1:62,500-scale topographic quadrangle maps to the geologic map, because the labeled latitude and longitude locations on the published geologic map did not register well with those on the topographic quadrangle maps. All faults with known offset were digitized as right-reading arcs and assigned right-reading decorated line patterns. The resulting digital map was attributed, converted to ARC/INFO, and then plotted to check for digitizing and attributing errors and to verify the fit with real-world coordinates (mathematically generated points of latitude and longitude).
