USGS Geoscience Data Catalog
Additional USGS Geoscience data can be found by geographic location or by publication series.
Derkey, Pamela D. , Johnson, Bruce R. , Lackaff, Beatrice B. , and Derkey, Robert E. , 1998, Digital geologic map of the Rosalia 1:100,000 quadrangle, Washington and Idaho: a digital database for the 1990 S.Z. Waggoner map: U.S. Geological Survey Open-File Report 98-357, 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
Abscissae (x-coordinates) are specified to the nearest not determined
Ordinates (y-coordinates) are specified to the nearest not determined
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.
Stephanie Z. Waggoner (1990) compiled the geology onto stable-base material;
A contractor (PacifiCad Inc., Spokane, WA) scanned the original stable-base geologic map (provided by the Washington Division of Geology and Earth Resources) and provided the U.S. Geological Survey (USGS) with an uncompressed TIFF file (reverse image, scanned at 600 dots per inch);
Bruce R. Johnson (USGS) converted the image to a vector geographic information system (GIS);
Pamela D. Derkey (USGS) and Beatrice B. Lackaff edited the vector data;
Pamela D. Derkey generated a GIS file for the point data, attached and attributed an interim geologic map data model (database).
Robert E. Derkey (WA DGER) digitized the point data and provided it in an Arc/Info GENERATE format file.

This dataset was developed to provide geologic map GIS of the Rosalia 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).

U.S. Geological Survey, 1993, 1:100,000-scale digital line graph (DLG) data - hydrography and transportation, Area 13 -- Northwestern states: U.S. Geological Survey Digital Line Graph, U.S. Geological Survey.
Attribute accuracy was verified by manual comparison
of the source with hard copy printouts and plots.
The horizontal positional accuracy for the digital data may be no
better than +/- 70 meters. It was tested by visual comparison of
the source with hard copy plots.
This digital dataset was produced from a previously
published report (Waggoner, 1990), and is considered
to be the best geologic map available for the area
at a scale of 1:100,000.
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 poygon
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?

Any hardcopies utilizing these data sets shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by the U.S. Geological Survey.
