Overview of attributes

The "Spatial Digital Database for the Geology of the San Pedro
River Basin in Cochise, Gila, Graham, Pima, and Pinal Counties,
Arizona" report (quib24k.pdf) contains a detailed description
of each attribute code and a reference to the associated
map symbols in the map source materials.  The database includes a geologic
linework arc attribute table, quib24k.aat, that relates to
the quib24k.co3 (contact look-up table), quib24k.st2
(structure look-up table), quib24k.lgu (linear geologic
units look-up table), and quib24k.ref (source reference
look-up table) files and a rock unit polygon attribute
table, quib24k.pat, that relates to the quib24k.ru (rock
unit look-up table) and quib24k.ref (source reference look-up
table) files.  Associated with this database is a geologic
marker point attribute table, quib24kp.pat that relates to
quib24kp.sym (symbol description look-up table) and
quib24kp.ref (source reference look-up table).

quib24kp.pat

Descriptions of the items identifying geologic map symbols are given in the point attribute table

Label Definition
pnttype Basic type of geologic point data being represented (for example, inclined foliation, fault attitude, etc). (This item also occurs in the QUIB24KP.SYM file.)
symbol Marker symbol number used by ArcInfo to identify type of geologic map symbol. Symbol numbers refer to the SCAMP2D.MRK markerset (Matti and others, 1997). (This item also occurs in the QUIB24KP.SYM file.)
strike Strike of bedding, foliation or cleavage. Strike is an azimuthal angle (measured in degrees from 0 to 360 in a clockwise direction from North).
dip Dip of bedding, foliation or cleavage. This value is an angle measured (in degrees from 0 to 90) down from the horizontal; thus a horizontal dip is 0 degrees and a vertical dip is 90 degrees.
ai_ang An interim value used to calculate sym$angle. The various structural map symbols in the SCAMP2D.MRK markerset (Matti and others, 1997) had to be rotated by different amounts to achieve their proper map orientation. For the strike and dip symbols, ai_ang = strike -270.
sym$ang The angle used to complete the mathematical rotation of the structural map symbol to its proper orientation on the map. The various point symbols in the SCAMP2D.MRK markerset (after Matti and others, 1997) had to be rotated by different amounts to achieve their proper map orientation. This value is the $angle pseudoitem value for the point.
source Numeric code used to identify the data source for the structural map symbol. Complete references for the sources are listed in the QUIB24KP.REF file.
