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, FAULTNAME,
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.  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 NESF-STRC.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 NESF-FLT.AAT.
