The scanned lines were vectorized with the CADCORE program.
Additional lines and point observations were added using a digitizer tablet with resolution of 0.001 inch.  Most positions on the map are estimated to be accurate closer than 30 m horizontally.  There is no elevation data in the database.
Logical_Consistency_Report:
Map elements were visually checked by the author for overshoots, undershoots, duplicate features, and other errors. The report is preliminary and has not been thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. The map was reviewed by another geologist for consistency with basic geologic principles and general conformity to USGS mapping standards.
Completeness_Report:
This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. Data is complete: no features were eliminated or generalized. There is no cross section and the ARC/INFO database lacks a unit properties table, although unit properties are described in the text explanation. A base map coverage is not included.

Lines were primarily positioned by interpretation of published preexisting geological mapping, thesis maps, and unpublished geological mapping. Lines were scanned from the basemap using a scanner with the following parameters:

Overview_Description:
Entity_and_Attribute_Overview:
The data is supplied in three formats. The first is a graphics file which can be sent to a plotter, The second is the multi-platform SDTS format, and the third is a UNIX based ARC/INFO format.
Available with all of this is ennis100.doc, A Word for Windows
format text file which contains a complete Description of Map Units.

DATA STRUCTURE - GRAPHICS

A postscript file ennis.eps created from an ARC/INFO graphics file.
This file was then converted to a printable RTL file using Image
Alchemy (v 1.11).

DATA STRUCTURE - SDTS

Not available

DATA STRUCTURE - ARC/INFO

ARC/INFO coverages are available as export files with the root of
individual coverages described below and the extension .e00

The database of the map consists of six coverages (ennis_poly;
ennis_line; ennis_text; ennis_dec; ennis_sym; and ennis_dip) and a
basemap coverage, ennis_base.  There are also nine additional
coverages (ennis_corr; struct_poly; struct_line; struct_dec;
struct_anno1; struct_anno2; struct_expln; source_line; source_anno),
eleven shade-key and text files (strshd1.key; strshd2.key;
source1.key; source2.key; rockshd1.key; rockshd2.key; rockshd3.key;
rockline1.key; rockline2.key; acknowledge.key; projection.key) that
are used in plotting the marginalia of the map (i.e. a correlation
of map units diagram, list of map unit symbols and names, a
structure map and explanation of symbols, a source map, a list of
references, projection information, and a list of acknowledgements.

ennis_poly coverage:  Contains all contact lines and labelpoints for
each polygon.  The character item LINE_TYPE and the integer item
LINE_CODE define the line type which bounds the polygon.  The
LINE_SYM item defines the symbol from the alcwrg.lin lineset used to
draw the lines. The UNIT_SYM defines the type of polygon using the
format of wyo.txt for geologic symbols; Proterozoic(!); Cambrian(_);
Pennslyvianian(&); Triassic(@). SHADE_SYM defines the unique color
for each polygon.

ennis_line coverage:  Contains faults, fold axis, and other
non-contact lines.  Faults that are contacts also appear in the
ennispoly coverage.  The line attributes in ennis_line are the same
as those in ennis_poly.

ennis_text coverage: Contains text poygon labels to appear on the
face of the map.  Also includes arcs that draw leaders from the text
to the appropriate polygons.  This coverage is for cartographic
purposes and does not include data critical to the database
information. The UNIT_SYM item defines the text to appear on the map
using the wyo.txt format.

ennis_dec coverage:  Contains lines which decorate faults. This
coverage is for cartographic purposes and does not include data
critical to the database information.

ennis_sym coverage: Contains lines which make up symbols which
decorate the map.  This coverage is for cartographic purposes and
does not include data critical to the database information.

ennis_dip coverage: Contains points associated with ennis_sym
coverage.  DIP item defines the dip that appears on the map.

ennis_base coverage:  Contains lines vectorized from a scanned image
(Ennis, MT 1:100,000-scale topographic sheet).

ennis_corr coverage: Contains polygons, arcs, and annotation
(subclass DXF) for the correlation of map units.

struct_poly coverage:  Contains all contact lines and labelpoints
for each polygon in the Structure Map. GEO_NAME item defines the
type of polygon. SHADE_SYM defines the unique color for each
polygon.

struct_line coverage: Contains faults, fold axes and other
non-contact lines on the Structure Map. Faults that are contacts
also appear in the structpoly coverage. LINE_SYM items defines the
significance of the line.

struct_dec coverage: Contains lines which decorate faults on the
Structure Map. This coverage is for cartographic purposes and does
not include data critical to the database information.

struct_anno1 coverage: Contains lines and annotation which describe
the Structure Map. . This coverage is for cartographic purposes and
does not include data critical to the database information.

struct_anno2 coverage:  Contains lines and annotation which describe
the Structure Map. This coverage is for cartographic purposes and
does not include data critical to the database information.

struct_expln coverage:  Contains lines and text points used to plot
the explanation of map symbols for the structure map. This coverage
is for cartographic purposes and does not include data critical to
the database information.

source_line coverage: Contains lines which appear on the Sources of
Geologic Data Map.

source_anno coverage: Contains text and leaders which appear on the
Sources of Geologic Data Map.

strshd1.key: ASCII text file used to create the boxes and
descriptive text for the Explanation of the Structure Map.

strshd2.key: ASCII text file used to create the text in the boxes
for the Explanation of the Structure Map.

source1.key: ASCII text file used to list the sources of geologic
data.

source2.key: ASCII text file used to list the sources of geologic
data.

rockshd1.key: ASCII text file used to create the shaded boxes,
symbols, and descriptive text for the List of Map Units.

rockshd2.key: ASCII text file used to create the shaded boxes,
symbols, and descriptive text for the List of Map Units.

rockshd3.key: ASCII text file used to create the shaded boxes,
symbols, and descriptive text for the List of Map Units.

rockline1.key: ASCII text file used to create the line symbol, and
descriptive text for the List of Map Units.

rockline2.key: ASCII text file used to create the line symbol, and
descriptive text for the List of Map Units.

acknowledge.key: ASCII text file used to list credits for work in
map compilation.

projection.key: ASCII text file used to list projection information
for the main map.

The importennis.aml file is included to constitute an ARC/INFO macro
language program that will import the data into ARC/INFO coverages
from the export (*.e00) format and organize the data into several
subdirectories.  The coverages containing data for the main geologic
map will be stored into the /covers-map directory.  The covers
containing data for the Correlation of map Units will be stored in
the /covers-corr directory.  The covers containing the data for the
the Source Map will be stored in the /covers-source directory.  The
covers containing the data for the Structure Map will be stored in
the covers-struct directory.  Images used in the plotting of the map
will be moved to the /images directory.  All ASCII key-files will be
placed in the /keys directory.  All documentation will be stored in
the /Documents directory.

The drawennis.aml file is included to constitute an ARC/INFO macro
language program that will extract information from the ennis
coverages to produce a graphics (.gra) file depicting the ennis
geologic map.  The graphics file can be viewed on screen or plotted
with appropriate equipment.

The aml program calls shadeset ctr269.shd; textset wyo.txt; linesets
alcwrg.lin, plotter.lin, carto.lin, alcgeol.lin; and image
cusgs_2_0.tif, so these are also included in the archive file.
Other files can be substituted, but special geologic characters may
not plot properly with a different font.
