Description:
Abstract:
This dataset was digitized by the U.S. Geological Survey EROS Data Center and U.S. Geological Survey Spokane Field Office for input into an Arc/Info geographic information systsem (GIS) The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.
Purpose:
This dataset was developed to provide a geologic map GIS of the Wallace 1x2 quadrangle 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 1:250,000 (e.g., 1:100,000 or 1:24,000)
Supplemental_Information:
This GIS consists of two major and Arc/Info datasets: one line and polygon file (wal250k) containing geologic contacts and structures (lines) and geologic map rock units (polygons), and one point file (wal250bc) containing breccia outcrops.

Data_Set_Credit:
Staff at EROS Data Center digitized the geologic map and prepared minimally attributed Arc/Info exchange-format files; R.J. Miller, R. Vandiver, M.C. Koenig (Eastern Washington University), and S.R. Munts (contractor) all participated in the initial edits of the dataset. William N. Kelley (contractor) completed the editing and attributing of arcs and polygons, and digitized the breccia point coverage (wal250bc).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy was verified by manual comparison of the source with hard copy printouts and plots.
Logical_Consistency_Report:
Polygon and chain-node topology present. Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. The neatline was generated by mathematically generating the four sides of the quadrangle, densifying the lines of latitude and projecting the file to Transverse projection.
Completeness_Report:
All geologic units were captured from Harrison and others (1986) at a scale of 1:250,000.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Arcs and points are probably no more accurate than 58 meters based upon measurements taken by comparing a paper plot with an original plate from the Harrison and others (1986) report.
