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>-
ID, LTYPE, PTYPE, PTTYPE, PATTERN, STRIKE, and DIP. LTYPE, PTYPE
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 HH_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 HR_POLY.PAT, and is defined by WIDTH 3,
OUTPUT 3, and TYPE I.  One coverage not described is HH_ANNO.
This coverage contains only annotations, and leader placement.
There are no defined attributes for this coverage.
