Overview of attributes

The databases in this report were compiled in ARC/INFO, a
commercial Geographic Information System (Environmental Systems
Research Institute, Redlands, California).  Almost all the
attributes in the various attribute tables of the coverages
included in the report are set or calculated by Arc/Info.  The
exceptions are "coveragename"-ID, LTYPE, PTYPE, PTTYPE, BKTYPE,
SAMPNO, STRIKE, and DIP.  "coveragename"-ID is required by internal
policy to be sequential. This ensures the highest compatibility of
our databases with other GISs. Therefore "coveragename"-ID is
calculated equal to "coveragename"#, which is a unique, sequential
integer assigned by Arc/Info to each data record.  LTYPE, PTYPE,
BKTYPE, and PTTYPE are author added items to the coverage AAT or
PAT that are used to describe the type of line (LTYPE), area (
PTYPE), block type (BKTYPE) or point (PTTYPE) being recorded.  All
coverages with AAT and PAT present include these items in the data
structure, although in some cases these items are not used (see
above).  Each has WIDTH 35, OUTPUT 35, TYPE C, except BKTYPE which
has WIDTH 6, OUTPUT 6, TYPE C.  STRIKE and DIP are author added
items to the coverage PAT that record information about the
orientation of planar geologic structures.  Both have WIDTH 3,
OUTPUT 3, TYPE I. These items are recorded in the tables XX-STR.PAT
of the structure coverages. KSPAR is an author added item that only
the table GAR-BLKS.PAT has that records information about the
percentage of K-feldspar collected at specific localities in the
map area.  It has WIDTH 35, OUTPUT 35, TYPE C.  The base map layers
are included for visual reference only and contain no data
attributes or attribute tables.
