What does this data set describe?

Title:
Digital analytical data from mineral resource assessments of National Forest lands in Washington
Abstract:
Unpublished mineral assessment reports of the Colville and Okanogan national forests (Chelan, Ferry, Okanogan, Pend Oreille, Skagit, Stevens, and Whatcom counties, WA) contain data on 3,934 samples analyzed for gold, silver, copper, lead, zinc, molybdenum, tungsten and uranium. Data presented here were obtained by R.A. Grant (1982a,b) for an assessment of the mineral potential of these national forests during 1979-1982 under a contract from the USDA-Forest Service.
Supplemental_Information:
No information was available from the contractor or the U.S. Forest Service to indicate analytical or laboratory specifications.

Why was the data set created?

This dataset was developed to provide geochemical data for the Colville and Okanogan national forests, WA for use in future spatial analysis by a variety of users.
This database is not meant to be used or displayed at any scale larger than 1:63,360 (e.g., 1:62,500 or 1:24,000).


How was the data set created?

  1. From what previous works were the data drawn?

    Grant, A.R., 1982, Summary report of findings and conclusions -- reconnaissance economic geology and probable future mineral activity target areas on the Colville National Forest, Washington: Colville National Forest, unpublished report, Okanogan, WA.

    Type_of_Source_Media: original stable-base film positives
    Source_Scale_Denominator: 63360
    Source_Contribution:
    Grant (1982a) is one of two sources of geochemical data in this digital database.

    Type_of_Source_Media: original stable-base film positives
    Source_Scale_Denominator: 63360
    Source_Contribution:
    Grant (1982b) is one of two sources of geochemical data in this database.

    Johnson, 1987 (source 3 of 3)
    Johnson, B.R., 1987, GSMODS - A personal mineral occurrence database system reference manual, version 1.01: U.S. Geological Survey Open-File Report 87-636, U.S. Geological Survey.

    Type_of_Source_Media: computer program
    Source_Contribution:
    This program was used to digitize locations of the geochemical sample (point) data.

  2. How were the data generated, processed, and modified?

    Date: 1998 (process 1 of 2)
    Geochemical sample sites were digitized from the original stable-base maps (assumed to be in a UTM zone 11 map projection) into GSMODS, ver. 1.01 (Johnson, 1987) as points.
    These point data were output to Arc/Info GENERATE-format files using the GSMGIS utility (G.I. Selner, written communication, 1994) and then imported into an Excel97 file format.

  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?

    Attribute accuracy was verified by manual comparison of the source with hard copy printouts and plots. Dave Boleneus estimated locations for eleven sample sites based on descriptions provided in Grant (1982a,b).

  2. How accurate are the geographic locations?

    The horizontal positional accuracy for the digital data averages +/- 107 meters, but may be no better than +/- 186 meters. It was tested by visual comparison of the source with hard copy plots for 110 sites.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This digital dataset was produced from unpublished reports (Grant, 1982a,b), and is considered to be a unique geochemical dataset for the area.

  5. How consistent are the relationships among the observations, including topology?

    Point data is given in latitude and longitude (decimal degrees).


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
