Abstract: Progress in Development
of Digital
Geologic Map Databases in Kansas
Several new geologic maps of individual
counties in Kansas, have recently been published with progress in development
of the Kansas Digital
Geologic Map Database. In coordination with the National
Geologic Map Database Project of the U.S. Geological Survey, programs at
the Kansas Geological Survey, have focused on new field mapping in areas
where published geologic maps were unavailable or deemed inadequate. This
effort is combined with innovations in database development from previously
published paper maps (commonly out-of-print) in those counties where maps
of reasonably good quality already exist. The Kansas mapping program has
established large scale (1:24,000) base maps as the standard for field
mapping and database development, a significantly larger target base map
scale than the 1:100,000 scale set for the national project.
This presentation demonstrates recent geologic
database development efforts and derived products. Techniques used by the
Kansas Survey for database development from previously published maps are
compared to the more common practice of direct digital
imaging (e.g., scanning).
The Survey's techniques, provide for integration of resulting data with
geologic data from new field work or with federal topographic map databases,
such as the USGS
digital
raster graphic map images. Recently published
maps, including Labette, Leavenworth, Wilson, Greenwood, Wyandotte, and
Chase counties are presented Methods used by the Kansas Survey to provide
access, via the Internet, to these maps and associated geologic data are
also explained.
