Abstract:
This data set maps and describes the geology of the Apache Canyon
7.5' quadrangle, Ventura and Kern Counties, California. Created using
Environmental Systems Research Institute's ARC/INFO software, the
data base consists of the following items: (1) a map coverage showing
geologic contacts, faults and units, (2) a separate coverage layer
showing structural data, (3) an additional point coverage which
contains bedding data, (4) a point coverage containing sample
localities, (5) a scanned topographic base at a scale of 1:24,000,
and (6) attribute tables for geologic units (polygons), contacts
(arcs), and site-specific data (points). The data base is accompanied
by a readme file and this metadata file. In addition, the data set
includes the following graphic and text products: (1) A jpg file
(.jpg) containing a browse-graphic of the geologic map on a 1:24,000
topographic base. The map is accompanied by a marginal explanation
consisting of a List of Map Units, a Correlation of Map Units, and a
key to point and line symbols. (2) A .pdf file of a geologic
explanation pamphlet that includes a Description of Map Units. (3)
Two postScript graphic plot-files: one containing the geologic map on
a 1:24,000 topographic base and the other, three accompanying
structural cross sections.
The geologic map database contains original U.S. Geological Survey
data generated by detailed field observation and by interpretation of
aerial photographs. The map was created by transferring lines and
point data from the aerial photographs to a 1:24,000 topographic base
by using a PG-2 plotter. The map was scribed, scanned, and
imported into ARC/INFO, where the database was built. Within the
database, geologic contacts are represented as lines (arcs), geologic
units as polygons, and site-specific data as points. Polygon, arc,
and point attribute tables (.pat, .aat, and .pat, respectively)
uniquely identify each geologic datum and link it to other tables
(.rel) that provide more detailed geologic information.
Purpose:
The data set for the Apache Canyon quadrangle has been prepared by
the Southern California Areal Mapping Project (SCAMP), a cooperative
project sponsored jointly by the U.S. Geological Survey and the
California Division of Mines and Geology, as part of an ongoing
effort to utilize a Geographical Information System (GIS) format to
create a regional digital geologic database for southern California.
This regional database is being developed as a contribution to the
National Geologic Map Data Base of the National Cooperative Geologic
Mapping Program of the USGS.
The digital geologic map database for the Apache Canyon quadrangle
has been created as a general-purpose data set that is applicable to
other land-related investigations in the earth and biological
sciences. The Apache Canyon database is not suitable for
site-specific geologic evaluations at scales greater than 1:24,000 (1
in = 2,000 ft).

Use_Constraints:
The Apache Canyon 7.5' geologic-map database should be used to
evaluate and understand the geologic character of the Apache Canyon
quadrangle as a whole. The data should not be used for purposes of
site-specific land-use planning or site-specific geologic
evaluations. The database is sufficiently detailed to identify and
characterize many actual and potential geologic hazards represented
by faults and landslides. However, it is not sufficiently detailed
for site-specific determinations or evaluations of those features.
Faults shown do not take the place of fault-rupture hazard zones
designated by the California State Geologist (see Hart, 1988).
Use of the Apache Canyon geologic-map database should not violate the
spatial resolution of the data. Although the digital form of the
data removes the constraint imposed by the scale of any derivative
maps, the detail and accuracy issues inherent in map scale
limitations are also present in the digital data. The fact that this
database was edited at a scale of 1:24,000 means that
higher-resolution data generally are 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 beyond the
intended resolution of the database. Similarly, although
higher-resolution data is incorporated at a few places, the
resolution of the combined output will be limited by the
lower-resolution data.
This report is preliminary and has not been reviewed for conformity
with U.S. Geological Survey editorial standards or with the North
American Stratigraphic Code. Any use of trade, product, or firm names
is for descriptive purposes only and does not imply endorsement by
the U.S. Government.

Data_Set_Credit:
Mapping of the Apache Canyon quadrangle benefitted from field visits by S.A.
Minor, K.S. Kellogg, and R.G. Stanley. Tephrochronologic data and
interpretations provided by A.M. Sarna-Wojcicki were invaluable for refining
the age of the Morales Formation. F.K. Miller generously scribed the
geologic base in preparation for scanning. Zenon Valin and Karen Wheeler
provided advice and assistance in scanning and subsequent processing of the
topographic base. Russell W. Graymer provided a thorough scientific review
of the manuscript and David Bedford reviewed the digital files, database
pamphlet, and metadata.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Geologic-map features in the Apache Canyon quadrangle were described
according to standard field methods. Consistent with these methods, the
database author has assigned standard geologic attributes to geologic
lines, points, and polygons identified in the database.
Geologic lines and points on 1:24,000 scale geologic maps are judged to
meet map-accuracy standards if they are located to within +/-15 meters,
relative to topographic or cultural features on the base map.
Lines and points that meet (or may not meet) this map-accuracy standard
are identified both in the digital database and on derivative
geologic-map plots.
Within the database, line and point data that are judged to meet the
map-accuracy standard are denoted by the attribute code .MEE. (meets)
in the appropriate data table; line and point data that may not meet
the map-accuracy standard are denoted by the attribute code .MNM. (may
not meet).
On any derivative geologic-map plot, line data that are judged to meet
the map-accuracy standard are denoted by solid lines; line data that
may not meet the map-accuracy atandard are denoted by dashed or dotted
lines. There is no cartographic device for denoting the map-accuracy
for geologic-point data (eg. symbols representing bedding, foliation,
lineations, etc.).
Logical_Consistency_Report:
Polygon and chain-node topology present.
The areal extent of the map is represented digitally by an
appropriately projected (Polyconic projection), mathematically
generated box. Consequently, polygons intersecting the lines that
comprise the map boundary are closed by that boundary. Polygons
internal to the map boundary are completely enclosed by line segments
which are themselves a set of sequentially numbered coordinate pairs.
Point data are represented by coordinate pairs.
Completeness_Report:
The geologic map and digital database of the Apache Canyon 7.5'
quadrangle contain new data that have been subjected to rigorous review
and are a substantially complete representation of the current state of
knowledge concerning the geology of the quadrangle.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The maximum transformation RMS error acceptable for 7.5' quadrangle
transformation and data input is 0.003 (1.8 meters). Horizontal
positional accuracy was checked by visual comparison of hard-copy plots
with base-stable source data.
Transformation data (initial DXF scan data format to ARC/INFO coverage)
for the Apache Canyon quadrangle are as follows:

Process_Description:
The geologic map information was scanned (initial raster scan in
MS-DOS TIF format, 1200 dots per inch) from a clear-film,
right-reading, 0.007 mil thickness, base-stable blackline positive
(made by contact photograph from the scribeguide) of the geologic map
at 1:24,000 scale. The auto-vectorized, non-attributed scan was
prepared by Optronics Specialty Company, Inc. and converted to an
ARC/INFO coverage using standard ARC/INFO commands. Registration and
transformation were subsequently completed (P.M. Cossette).
Geologic lines and polygons are represented in the geology coverage.
Geologic points such as attitudes were digitized into a separate
geologic points coverage using a Mayline Futur-Matic digitizing table
(P.M. Cossette).
Lines, points, and polygons were edited and attributed using standard
ARC/INFO commands. Digitizing and editing artifacts significant
enough to display at a scale of 1:24,000 were corrected (P.M.
Cossette).
The base map image was prepared by scanning a scale-stable clear-film
of the U.S. Geological Survey, 1:24,000 Apache Canyon 7.5'quadrangle
(1991) topographic map. Scanning was done using a Contex FSC-8000
DSP scanner, at a resolution of 500 dpi. For plotting purposes in
order that geologic data not be obscurred or occluded by the
topographic base map data, the monochromatic raster scan was
converted to grid format in ARC/INFO GRID, and color reassigned. No
elements of the base layer are attributed. The original scan (in
GEOTIFF format) of the base map is provided for reference only (Z.
Valin, K. Wheeler, and P.M. Cossette).

P-DIPDIR azimuthal direction of dip
To date, there is no other way to indicate to the user the
cardinal direction of dip using the traditional convention
(traditional geologic notation allows a quadrant
designation following the dip value).
4) apache_ptsorn - structural line ornamentation
The point data included in apache_ptsorn allow a visual representation of
the type of structural linear feature, e.g. anticline and syncline
symbols. The items P-TAG and P-SYMB link the point tag to its full
description in points.rel and call up the appropriate point symbol from
geoscamp2.mrk.

7) apache_xs - cross-section lines
Three cross-section analyses are represented on the Apache Canyon
quadrangle map plot by three lines contained in the coverage
apache_xs. Their definitions are identical to those contained in
apache_ldr. These cartographic line entities are similarly
attributed with only a single attribute, L-SYMB, and all have the
same value, 1. The cross-section lines AA', BB', and CC' are
designated by annotation contained in the annotation subclass,
xsection.
The data dictionary tables, lines.rel and points.rel each
contain three items: L-TAG and P-TAG establish the links
between the .aat, and the .pat to the respective data
tables. The items L-DEF and P-DEF, respectively provide the
coded definition for an entity. The items L-EXP and P-EXP
provide a parsed explanation of the code contained in the
corresponding -DEF items.
