Abstract
This geologic map was prepared as part of a study of digital
methods and techniques as applied to complex geologic maps. The
geologic map was digitized from the original scribe sheets used to
prepare the published Geologic Map of Wyoming (Love and Christiansen,
1985). Consequently, the digital version is at 1:500,000 scale using
the Lambert Conformal Conic map projection parameters of the State base
map. Stable base contact prints of the scribe sheets were scanned on
a Tektronix 4991 digital scanner. The scanner automatically converts
the scanned image to an ASCII vector format. These vectors were
transferred to a VAX minicomputer, where they were then loaded into
ARC/INFO. Each vector and polygon was given attributes derived from
the original 1985 geologic map.
