OKLAHOMA CITY -- Digital map data sets of surficial geologic features for Oklahoma have just been released on the Internet by the U.S. Geological Survey. The Internet Uniform Resource Locator (URL) for information on the data sets is:
These data sets, developed in cooperation with the State of Oklahoma, Office of the Secretary of the Environment, may be useful for a broad variety of people including farmers, science teachers, highway engineers, oil producers, and many others, according to the USGS. The data sets are designed especially for use with Geographic Information Systems (GIS) for computerized mapping and spatial analysis. They can be used to make geologic maps, and determine approximate areas and locations of various geologic units and faults.
The digital maps of the Oklahoma panhandle are based on Hydrologic Investigation Atlases published on paper by the U.S. Geological Survey in the late 1960's and early 1970's. The digital maps of Oklahoma excluding the panhandle are based on Hydrologic Atlases published on paper by the Oklahoma Geological Survey in the 1970's and 1980's. The digital maps were developed by scanning the photographic negatives of the original paper maps. The data sets were developed as part of a statewide aquifer vulnerability study to show surficial geology, faults, geologic beds, anticlines, synclines, and monoclines within Oklahoma.
The data sets also are available on diskettes published in U.S. Geological Survey Open-File Reports. Each report contains one to four diskettes and all the data sets are available in nonproprietary and ARC/INFO formats. The diskettes are available for purchase for ten dollars each from the U.S. Geological Survey, Earth Science Information Center, Open-File Reports Section, Box 25286, Denver, Colorado, 80225 (303) 202-4200.
