Overview of attributes

Version 1.0 of the Sunnymead 7.5' quadrangle comprises three ARC/INFO coverages, of which two contain geologic data, and one contains cartographic features:  sun_geo (geology), sun_str (structural data), and sun_ano (annotation and leaders).
Geologic data represented by line entities and the polygons they delineate are contained in the coverage SUN_GEO.  For display purposes, the annotation coverage contains one annotation subclass:  anno.geo contains unit labels.
Geological point data includes site-specific information describing the types and the orientation of bedding, foliation, and lineations.  Annotation is respective dip and plunge values associated with individual point data.

sun_geo.pat

Geologic units (LABL) and their corresponding names (NAME) identified in the Sunnymead 7.5' quadrangle

Label Definition
LABL geologic map unit label, in plain text
PLABL Geological map unit label used to generate plot labels with relevant stratigraphic symbols. The geologic units with LABL designating Mesozoic (Mz) have keystroke substitute characters, }, that call their corresponding symbols from the Stratagem Font Group. Geologic map unit labels will plot on derivative map plots with appropriate stratigraphic symbols if PLABL is used as the source for unit labels.
SHD polygon color (as integer value) from shadeset alc1.shd (included in the symbols package)
SHDFIL polygon fill pattern (as integer value) from shadeset geology2.shd (included in the symbols package)
NAME Geologic name of map unit (see list under LABL attribute)

sun_geo.aat

Geologic features such as contacts and faults that bound rock-unit polygons

Label Definition
LTYPE Description of types of lines on the geologic map (contact, fault).
L-SYMB stores appropriate line symbol value from the lineset geoscamp2.lin

sun_str.pat

Geological point data includes site-specific information describing the types and the orientation of bedding, foliation, and lineations. One annotation subclass is included in the geologic points coverage, SUN_STR which displays the respective dip and plunge values associated with individual point data.

Label Definition
PTTYPE describes type of point data (bedding, horizontal bedding, foliation)
P-SYMB Coded integer value that relates point to cartographic point symbol in markerset geoscamp2.mrk
STRIKE Azimuthal strike of planar feature
DIP Dip of planar feature

sun_ano.aat

Annotation leaders

Label Definition
L-SYMB Coded integer value (1) that relates arcs to cartographic line symbol in lineset geoscamp2.lin
