E00 File Information
--------------------

The following coverages have been converted to E00 files and exist in either
the base or geology folders.

Original name of coverage: HYD1668
E00 File: hyd1668.e00
Features: Arcs and Polygons
Description: Hydrology features

Original name of coverage: BAS1668
E00 File: bas1668.e00
Features: Arcs and Points
Description: Base line and point features, not including hydrology

Original name of coverage: NTL1668
E00 File: ntl1668.e00
Features: Arcs and Polygons
Description: Neatline of map

Original name of coverage: GEO1668
E00 File: geo1668.e00

Description: Geological contacts and polygons
This coverage contains the following associated info files:
   GEO1668.LEG - Legend description of CODE values
   GEO1668.LVL - Description of levels in legend info file
   GEO1668.SYM - Symbols used for each CODE value
   GEO1668.EXT - Description of items contained in external tables

Original name of coverage: LIN1668
E00 File: lin1668.e00
Features: Arcs
Description: Geological line features

Original name of coverage: PNT1668
E00 File: pnt1668.e00
Features: Points
Description: Geological point features
This coverage contains the following external tables:
   PNT1668.PXT - External table common to all polygon/point features
   PNT1668.MIN - Mineralogical occurrences
   PNT1668.NAT - Natural resource areas
   PNT1668.AGE - Age/chronology analysis

Notes
-----

Info files contain legend information of geological features.  Records in the
GEO1668.LEG info file are related to feature attributes using the CODE
item/field.  Values of the LEVEL item/field in the GEO1668.LVL info file
are related to the LEVEL items in the GEO1668.LEG info file.
The GEO1668.SYM info file list the symbols used for each of the CODE values
listed in the GEO1668.LEG info file.

External tables contain additional attributes of features as supplied by the
author that do not conform to Cartographic Digital Standards.  Records in the
external table are related one-to-one to feature attributes using the -LINK
item/field.  The GEO1668.EXT info file lists the descriptions of each item
in each external table.

Abbreviations for GSC Special Characters
----------------------------------------
 
These abbreviations occur in the values of the item CODE

geological units in the geological legend info file.

Abbreviations are always two letters starting with a capital.
 
A dash separates the special character abbreviation from the rest
of the unit reference letters (eg. Mz-g is (Mesozoic)g).
 
Multiple special characters in a unit reference will be strung
together as one (eg. (Mesozoic)(Archean)g -> MzAr-g
 
When a dash, comma or slash exists in a unit reference, it is
replaced with an underscore (eg. Mz-g, Mz-h -> Mz-g_Mz-h).
 
Age modifiers are a single case sensitive letter that appears before
the special character abbreviation (eg. (Late)(Mesozoic)g -> LMz-g
 
l - lower                    E - early
m - middle                   M - middle
u - upper                    L - late
