资源简介：
The Geologic Map of Arizona was compiled at a scale of 1:500,000 by
Eldred D. Wilson, Richard T. Moore and John R. Cooper, in 1969 and
reprinted in 1977, 1981, and 1983.
Comparison of an acetate copy of the 1983 map with existing paper
copies of earlier maps shows some updating of the original by 1983.
This 1983 acetate was scanned and vectorized by Optronics Specialty Co., Inc.
in 1998, and put into an Arc/Info geographic information system (GIS).
The digital geologic map database can be queried in many ways to
produce a variety of derivative geologic maps.
