Overview of attributes

Version 1.0 of the Chewelah 30' x 60' geologic map database comprises six
coverages, of which two contain geologic data, two contain DLG derived
geo-reference data, and two contain cartographic line entities.
Geologic data represented by line entities and the polygons they delineate
are contained in the coverage CHEW_GEO. For display purposes, the geology
coverage contains two annotation subclasses: anno.geo contains unit labels,
and anno.fault contains formal, fault names.
Feature attribution and item definitions are as follows:

PLABL	coded geologic map unit label used to generate plot labels with
relevant stratigraphic symbols.  The geologic units with LABL designating
Paleozoic (Pz), Cambrian (C), Mesozoic (Mz), and Triassic (Tr) have PLABL
with substitute characters, |, _, }, and ^ respectively, that call their
corresponding symbols from the GeoAge Font Group.  Geologic map unit
labels will plot on derivative map plots with appropriate stratigraphic
symbols if PLABL is used as the source for unit labels.  The GeoAge
Font Group is accessed through geofont.txt.  The GeoAGe Font
Group and relevant information are available via annonymous FTP:

L-SYMB	stores appropriate line symbol value from the lineset
geoscamp2.lin (included in the data package)
L-NAME	formal name of fault
Geological point data includes site-specific information describing the
types and the orientation of bedding, foliation, and lineations. One
annotation subclass is included in the geologic points coverage,
CHEW_PTS: anno.dip displays the respective dip and plunge values
associated with individual point data.

P-SYMB		calls the point-type from the markerset geoscamp2.mrk
(included in the data package)
P-TAG		point tag which consists of a character(s) and numerical
value, e.g. FN42, allows the user to relate the point entity to its
corresponding definition in the data table, points.rel
Point types (quantitative orientation data) in chew_pts.pat and their
corresponding, abbreviated descriptions from points.rel:
>B1	Bedding, horizontal, sedimentary rocks
>B2	Bedding, inclined, sedimentary rocks
>B4	Bedding, vertical, sedimentary rocks
>B6	Bedding, overturned, sedimentary rocks
>B11	Bedding, wavy or crinkled, inclined, sedimentary rocks
>B27	Bedding, inclined, volcanogenic rocks
>FN13	Foliation, primary igneous, inclined
>FN14	Foliation, primary igneous, vertical
>FN42	Foliation, metamorphic, inclined
>FN43	Foliation, metamorphic, vertical
>CLV2	Cleavage, inclined
>CLV4	Cleavage, vertical
>L12	Lineation, crushed and streaked mineral grains, horizontal
>L14	Lineation, crushed and streaked mineral grains, inclined
>L37	Lineation, metamorphic, minor fold axis
P-DIP		the dip of planar features
P-STRIKE	the azimuth strike of planar features
P-DIPDIR	azimuthal direction of dip
At present, it is not possible to indicate the cardinal direction of dip
using traditional conventions (traditional geologic notation allows a
quadrant designation following the dip value).
P-PLUNGE	lineation plunge value
P-BEARING	azimuthal bearing of plunge
The two coverages that provide base-map (DLG derived) geo-reference
information are CHEW_HYPS (topographic contour data) and CHEW_TRANS
(cultural data/roads).  Both are line coverages.
In order to facilitate plotting of the topographic information available
in CHEW_HYPS, original DLG-derived attribution was retained and two
additional attributes added, LTYPE and ELEV.  The added attributes allow
the user to descriminate between, and selectively plot, contour data.
Similarly, in addition to the original DLG-derived transportation
attribution available in CHEW_TRANS, three additional attributes were
added, LTYPE, USROUTE, and STROUTE.  They permit the user to identify and
selectively plot the various road types included in the DLG data.
Cartographic line entities are contained in CHEW_XS (two cross-section
traces) and CHEW_LDR (unit label leaders).  These line entities have only
one attribute, L-SYMB, and all have the same value, 1.
