USGS Geoscience Data Catalog
Additional USGS Geoscience data can be found by geographic location or by publication series.
Rember, W.C., Bennett, E.H., and Kayser, H.Z., 2001, Spatial digital database for the geologic map of the east part of the Pullman 1°x2° quadrangle, Idaho: U.S. Geological Survey Open-File Report 01-262, U.S. Geological Survey, Menlo Park, CA.Online Links:
This is a Vector data set. It contains the following vector data types (SDTS terminology):
The map projection used is Transverse Mercator.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 12.74271184007
Ordinates (y-coordinates) are specified to the nearest 12.74271184007
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.
Optronics Specialty Corp., Inc. scanned the Rember and Bennett (1979) geologic map and provided minimally attributed ArcInfo interchange-format files to the USGS;
Helen Z. Kayser (contractor) attached and attributed an interim geologic map data model; and
Michael Zientek (USGS) and Pamela D. Derkey (USGS) visually compared the hard copy plots with the source documents.

This dataset was developed to provide a geologic map GIS of the east part of the Pullman 1:250,000 quadrangle for use in future spatial analysis by a variety of users. These data can be printed in a variety of ways to display various geological features or used for digital analysis and modeling. 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).
Rember, William C., and Bennett, Earl H., 1979, Geologic Map of the Pullman Quadrangle, Idaho: Geologic Map Series, Idaho Bureau of Mines and Geology, Moscow, Idaho.
Attribute accuracy was verified by manual comparison of the source with hard copy printouts and plots.
+/- 55 meters
This digital geologic map is wholly derived from Rember, and Bennett (1979). Scratch boundaries were added by the author (Kayser, 2001).
Polygon and chain-node topology present. Polygons intersecting the neatline area 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 do duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment.
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.
