Title:
Digital mineral resource maps of phosphate and natural aggregate for the Pacific Northwest: a contribution to the Interior Columbia Basin Ecosystem Management Project
Abstract:
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 for the Interior Columbia Basin Ecosystem Management Project (ICBEMP), a US Forst Service and Bureau of Land Management interagency project. The various digital maps and data files which were provided by the USGS, and which are available in this and other reports, are being used in a GIS-based ecosystem assessment which includes a comprehensive analysis of past, present, and future ecosystem conditions within the general area of the Columbia River Basin east of the Cascade Mountains.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
    • Arthur A. Bookstrom
    • Gary L. Raines
    • Bruce R. Johnson
  2. Who also contributed to the data set?
    This product would not exist without the input of the many geoscientists whose work was essential to making both state geologic maps and mineral resources databases. This effort would not be possible without those past products and others from the following agencies: the US Geological Survey, the California Division of Mines and Geology, the Idaho Bureau of Mines and Geology, the Montana Bureau of Mines and Geology, the Nevada Bureau of Mines and Geology, the Oregon Department of Geology and Mineral Industries, the Utah Geological and Mineral Survey, the Geological Survey of Wyoming, and the Washington State Department of Natural Resources. We particularly acknowledge Patrick Geehan, the Bureau of Land Management project coordinator for the Interior Columbia River Basin Ecosystem Management Project, for recognizing the importance of geology to ecosystem management and for supplying funds to digitize the Washington, Idaho, and Montana state geologic maps. We also acknowledge James D. Bliss for his helpful review of this report.

Why was the data set created?

The goal of the ICBEMP management strategy is to provide management tools to sustain or restore ecosystem integrity and produce desired condistions, uses, products, values, and services over the long term. The intent of the project is to understand the ramifications of management practices or distrubances both in the area subject to the practice or disturbance as well as effects which may be removed, in time and space, from the area.

  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 lines and polygons were edited and proofed, attributes were added and proofed, the maps were transformed from scanner units to geographic coordinates, and finally, map distortions were removed by rubber-sheeting.
