Title: Geologic map of the Silver Lake quadrangle, Cowlitz County,
Washington

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract: This digital map database, compiled from previously published
and unpublished data, and new mapping by the authors, represents the
general distribution of bedrock and surficial deposits of the Silver
lake 7.5 minute quadrangle. The database delineates map units that are
identified by general age and lithology following the stratigraphic
nomenclature of the U.S. Geological Survey. The scale of the source maps
limits the spatial resolution (scale) of the database to 1:24,000 or
smaller.

Purpose: This database and accompanying plot files depict the
distribution of geologic materials and structures at a regional
(1:24,000) scale. The report is intended to provide geologic information
for the regional study of materials properties, earthquake shaking,
landslide potential, mineral hazards, seismic velocity, and earthquake
faults. In addition, the report contains new information and
interpretations about the regional geologic history and framework.
However, the regional scale of this report does not provide sufficient
detail for site development purposes. In addition, this map does not
take the place of fault-rupture hazard zones designated by the Oregon
State Geologist (REF?). Similarly, the database cannot be used to
identify or delineate landslides in the region.

Supplemental_Information: Procedures_Used: The databases in this report
were compiled in ARC/INFO, a commercial Geographic Information System
(Environmental Systems Research Institute, Redlands, California), with
version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth,
1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The files are
in either GRID (ARC/INFO raster data) format or COVERAGE (ARC/INFO
vector data) format. Coverages are stored in uncompressed ARC export
format (ARC/INFO version 7.x). ARC/INFO export files (files with the
.e00 extension) can be converted into ARC/INFO coverages in ARC/INFO
(see below) and can be read by some other Geographic Information
Systems, such as MapInfo via ArcLink and ESRI\'s ArcView (version 1.0
for Windows 3.1 to 3.11 is available for free from ESRI\'s web site:
http://www.esri.com). The digital compilation was done in version 7.1.1
of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon
and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991).
The geologic map information was digitized from stable originals of the
geologic maps at 1:24,000 scale. The author manuscripts (pen on mylar
and pen on paper) were scanned using a Anatek rasterizing color scanner
with a resolution of 600 and 400 dots per inch. The scanned images were
vectorized and transformed from scanner coordinates to projection
coordinates with digital tics placed by hand at quadrangle corners. The
scanned lines were edited interactively by hand using ALACARTE, color
boundaries were tagged as appropriate, and scanning artifacts visible at
1:24,000 were removed.

Use_Constraints: Uses of this digital geologic map should not violate
the spatial resolution of the data. Although the digital form of the
data removes the constraint imposed by the scale of a paper map, the
detail and accuracy inherent in map scale are also present in the
digital data. The fact that this database was edited for a scale of
1:24,000 means that higher resolution information is not present in the
dataset. Plotting at scales larger than 1:24,000 will not yield greater
real detail, although it may reveal fine-scale irregularities below the
intended resolution of the database. Similarly, where this database is
used in combination with other data of higher resolution, the resolution
of the combined output will be limited by the lower resolution of these
data.
