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, and PTTYPE are author
added items to the coverage AAT or PAT that are used to describe the
type of line (LTYPE), area (PTYPE), 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.  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 only recorded in the table PA_UM-
SR.PAT.  FAULTNAME is an author added item the coverage AAT that
records information about the names of faults in the map area.  It
has WIDTH 35, OUTPUT 35, TYPE C.  FAULTNAME is only recorded in the
table PA_UM-FLT.AAT.  The base map layers (pa_um-dr, pa_um-cu, pa_um-
topo) are included for visual reference only and contain no data
attributes or attribute tables.

This report combined with the explanatory pamphlet: pamf.ps, pamf.pdf, pamf.txt.

PA_UM-PY.PAT

Attribute table of PA_UM-PY.

Label	Definition
`PTYPE`	Geologic unit label

PA_UM-PY.AAT

Attribute table of PA_UM-PY.

Label	Definition

PA_UM-SR.PAT

Attribute table of PA_UM-SR.

Label	Definition
`PTTYPE`	The type of planar feature which was observed and the orientation of which was measured at this point.
`DIP`	The inclination of planar structures measured in degrees down from horizontal.
