Overview of attributes

The databases in this report were compiled in ARC/INFO, a commercial
Geographic Information System (Environmental Systems Research
Institute, Redlands, California), with version 3.0 of the menu
interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991,
Wentworth and Fitzgibbon, 1991).  Consequently each feature attribute
table contains attributes generated by the software to describe the
topology of the geographic features.  In addition, the following
integer fields are included by ALACARTE:
>SEL   user defined field used to save a selected set
>SYMB  user defined field used to save symbol assignments (such as color)
The geologic linetypes are ALACARTE line types that correlate with the
geologic line symbols in the ALACARTE line set GEOL61.LIN according to
the ALACARTE lines lookup table (GEOL61.LUT).
