USGS Geoscience Data Catalog
Additional USGS Geoscience data can be found by geographic location or by publication series.
Lewis, Reed S., and Derkey, Pamela D., 1999, Digital geologic map of part of the Thompson Falls 1:100,000 quadrangle, Idaho: U.S. Geological Survey Open-File Report 99-438, U.S. Geological Survey, Spokane WA.Online Links:
This is a Vector data set. It contains the following vector data types (SDTS terminology):
Planar coordinates are encoded using coordinate pair
Planar coordinates are specified in METERS
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.4.
The flattening of the ellipsoid used is 1/294.98.
Reed S. Lewis (contractor) compiled the geology onto stable-base material; Optronics Specialty Co., Inc. scanned the geologic map and provided minimally attributed Arc/Info EXPORT-format files to the USGS; Pamela D. Derkey (USGS) imported the files, transformed them to UTM zone 11 (with a y-shift) and attached and attributed an interim geologic map data model; Thomas P. Frost (USGS) visually compared the hard copy plots with the source; Jon R. Oblad (EWU) annotated the point data for output at a scale of 1:100,000.

This dataset was developed to provide geologic map GIS of the Idaho portion of the Thompson Falls 1:100,000 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 1:100,000 (e.g., 1:62,500 or 1:24,000).

Attribute accuracy was verified by manual comparison
of the source with hard copy printouts and plots.
The horizontal positional accuracy for the digital data is no
better than +/- 7 meters based on the transformation RMS error.
It was tested by visual comparison of the source with hard copy
plots.
All geologic units were compiled from previously existing
geologic maps ranging in scale from 1:24,000 to 1:250,000.
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 UTM
zone 11 (with a y-shift).
Are there legal restrictions on access or use of the data?
