Overview of attributes

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).

>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.
