Overview of attributes

The databases described in this report were compiled in ARC/INFO,
a commercial Geographic Information System by Environmental
Systems Research Institute.  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 being <COVER>-
and PTTYPE are author added aspects of the coverages added to the
PAT or AAT and are used to describe the type of line (LTYPE),
area (PTYPE), point or arcmarker (PTTYPE).  LTYPE and PTTYPE are
each defined with WIDTH 35, OUTPUT 35, and TYPE C (character).
PTYPE is defined with WIDTH 5, OUTPUT 5, and TYPE C.  STRIKE and
DIP are only present in PARA_DIP.PAT, because they describe
bedding orientation of point objects.  Each is defined with WIDTH
and OUTPUT of 3, and TYPE I (integer).  PATTERN was another
author-added attribute only in PARA_POLY.PAT, and is defined by
WIDTH 3, OUTPUT 3, and TYPE I.  The data in PATTERN correlates
directly with specific values in the PTYPE field.  One coverage
not described is PARA_ANNO.  This coverage contains only
annotations, and leader placement.
