Title:
Geologic data sets for weights-of-evidence analysis in northeast Washington--1. Geologic raster data
Abstract:
This dataset contains the combination of geology data (geologic units, faults, folds, and dikes) from 6 1;100,000 scale digital coverages in eastern Washington (Chewelah, Colville, Omak, Oroville, Nespelem, Republic). The data was converted to an Arc grid in ArcView using the Spatial Analyst extension.
Supplemental_Information:
Geologic data sets were preliminary Arc/Info coverages obtained from Washington Department of Natural Resources.

  7. How does the data set describe geographic features?
    Entity_and_Attribute_Overview:
    These four Arc/InfoArcInfo Grids (newageol, newafaul, newafold, newadike) were attributed with geologic codes from the vector coverages obtained from Washington Department of Natural Resources. They were created from a vector coverage. Newageol.vat and newadike.vat have 3 items of information - value, count, and s-value. Value is a number, while s-value is a character item containing geologic symbol code for a geologic unit and its age. Count is how many cells have that value. The other two grid tables (newafold.vat and newafaul.vat) only have count and value items. The value item is a number, which is a fold or fault type. These are described in appendix b, Causey, and others, 2000.

Why was the data set created?

Four grids (newageol, newafaul, newafold, newadike) were built to use in a weights-of-evidence analysis of mineral deposits and mineral activity. The requirements of a proposed modeling procedure necessitated converting the vector data to gridded raster files. A new lithologic classification was also created to provide uniform terminology for rock units mapped within the study area.

  2. How were the data generated, processed, and modified?
    Date: 1998 (process 1 of 2)
    Arc/InfoArcInfo vector coverages for six 1:100,000-scale quadrangles were combined using the PUT command in ArcEdit for each of four themes (geology, faults, folds, and dikes. The combined coverages were cleaned using default tolerances. The four resulting coverages were converted to a GRID in ArcView 3.1 with Spatial Analyst Extension. The cell sizes were set at 50 meters for newageol and newafold; 100 meters for newfaul; and 200 meters for newadike. The extents were the extent of the compiled coverages.
