Open-File Report 03-501 metadata
Map units (polygons) are described in the polygon attribute table (kls-geol.pat). The identities of the map units are recorded in the PTYPE field by map label (i.e. Qia). For a description of the map units, consult the PostScript or PDF explanation pamphlets in this report or the printable map sheet.
Geologic lines (arcs) are recorded as strings of vectors and are described in the arc attribute table (kls-geol.aat). They define the boundaries of the map units, the faults, and the map boundaries. These distinctions, including the geologic identities of the unit boundaries, are recorded in the LTYPE field. Attributes for geologic lines generally follow a scheme of the type of geologic line (i.e. fault), followed by a locational and/or scientific modifier (i.e. approx. located or queried).
