Summary
Abstract: These data are digital facsimiles of the original 1984 Engineering Aspects of
Karst map by Davies and others. This data set was converted from a printed map
to a digital GIS coverage to provide users with a citable national scale karst
data set to use for graphic and demonstration purposes until new, improved data
are developed. These data may be used freely with proper citation. Because it
has been converted to GIS format, these data can be easily projected, displayed
and queried for multiple uses in GIS. The karst polygons of the original map
were scanned from the stable base negatives of the original, vectorized, edited
and then attributed with unit descriptions. All of these processes potentially
introduce small errors and distortions to the geography. The original map was
produced at a scale of 1:7,500,000; this coverage is not as accurate, and
should be used for broad-scale purposes only. It is not intended for any
site-specific studies.
