Geologic Map and Digital Database of the Cougar Buttes 7.5' Quadrangle, San Bernardino County, California

The ARC/INFO version of the Digital Geologic Map of the Cougar Buttes 7.5'quadrangle consists of five coverages:
1) coug_geo - geology
Geologic units are delineated by geologic line entities and described by polygons which are attributed with the following set of attribute items in coug_geo.pat. For display purposes, the geology coverage contains three annotation subclasses: anno.geo contains unit labels, anno.fault contains formal fault names, and anno.twn_rnge contains township and range data.

PLABL coded geologic map unit label used to generate plot labels with relevant stratigraphic symbols. The geologic units with LABL MzPrgg (Mesozoic or Proterozoic) and Prgn (Proterozoic) appear as }<gg, <gn respectively in the item PLABL. The replacement characters 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 of unit labels. The Stratagem Font Group is accessed through geofont.txt, and is included in the data package.
TAG enables identification of polygons, within a unit, of which the geology is sufficiently distinct from that of the overall unit. The default designation is the unit label with the suffix A. Polygons representing unique properties other than the default can be identified with suffixes B, C...etc. All polygons in the Cougar Buttes quadrangle are designated by the suffix A.
SHDPS polygon color from shadeset scamp2.shd (included in the data package)
NAME geologic name of each unit
SHDFIL polygon fill pattern from shadeset geology2.shd (included in the data package)
Geologic lines, which include features such as faults, contacts, and marker horizons are attributed with the following set of feature attribute items contained in coug_geo.aat. (A complete description of each line type is available in the data table, lines.rel.)

The data dictionary tables, lines.rel and points.rel each contain three items: L-TAG and P-TAG establish the links between the .aat, and the .pat to the respective data tables. The items L-DEF and P-DEF, respectively provide the coded definition for an entity. The items L-EXP and P-EXP provide a parsed explanation of the code contained in the corresponding -DEF items.
