Title:
Digital maps of compositionally classified lithologies derived from 1:500,000-scale geologic maps for the Pacific Northwest: a contribution to the Interior Columbia Basin Ecosystem Management Project
Abstract:
This report describes the contents of a digital data set (approximately 269 MB) which consists of Arc/Info Export format files and associated macro programs. This report is one in a series of digital maps, data files, and reports generated by the US Geological Survey to provide geologic process and mineral resource information to the Interior Columbia Basin Ecosytem Management Project (ICBEMP). The various digital maps and data files are being used in a GIS-based ecosystem assessment including an analysis of diverse questions relating to past, present, and future conditions within the general area of the Columbia River Basin east of the Cascade Mountains.

  2. How were the data generated, processed, and modified?
    Date: unknown (process 1 of 2)
    The state geologic maps were processed digitally, as follows: the source material was scanned, the scanned image was vectorized and topologically structured, the lines and polygons were edited and proofed, attributes were added and proofed, the map was transformed from scanner units to geographic coordinates, and finally, map distortions were removed by rubber-sheeting.

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Complete
  5. How consistent are the relationships among the observations, including topology?
    The sources of geologic information for the compositionally classified lithology maps were the geologic maps of California (Jennings, 1977), Idaho (Bond and Wood, 1978), Montana (Ross, Andress and Witkind, 1955), Nevada (Stewart and Carlson, 1978), Oregon (Walker and MacLeod, 1991), Utah (Hintze, 1980), Washington (Hunting and others, 1961), and Wyoming (Love and Christiansen, 1985). The individual state geologic maps were combined to produce a composite geologic map of the Pacific Northwest with over 800 rock units, as described in Johnson and Raines (1995).
