Societal Value Of Geologic Maps

An economic analysis by the US Geological Survey's National Geologic Mapping Program that describes (1) geologic maps and their use as a fundamental data base, (2) a rigorous benefit-cost model for valuing geologic map information, and (3) the economic issues associated with determining whether or not a geologic map is a public good.

Describes: geologic maps and their use as a fundamental data base, a rigorous benefit-cost model for valuing geologic map information, and the economic issues associated with determining whether or not a geologic map is a public good. Maps, charts and tables, some in color. Extensive bibliography.

Geologic maps: a few lucky geologists make them; many geoscientists, engineers, and planners use them; untold scores of people wonder what they are all about. Perhaps the most common question we are asked, those few of us who do make geologic maps, is, simply,“What is a geologic map?” This query is often followed by “What are geologic maps used for?,” “Hasn’t it been mapped before?,” and, if the person is really inquisitive, “What do all those lines, colors, and symbols represent?” It must be a puzzling sight - a lone geologist, often miles from the nearest road, looking at rocks, putting lines on a map or aerial photograph. One rightfully wonders what that person is doing. This pamphlet answers these questions and points out the value and many uses of geologic maps.
