Kentucky Mine Mapping Information System
This Website provides Internet access to view and
download (1) all known mined out areas (polygons) digitized by the Kentucky
Revenue Cabinet (2) individual Mine reports from the Mines and Minerals
database, and (3) Scanned images of Engineering drawings (mine maps)
submitted to Mines and Minerals since January 2002 and selected earlier
Kentucky Division of
Geographic Information (DGI)
As part of the Commonwealth Office of Technology, the
Division of Geographic Information (DGI) is responsible for encouraging,
coordinating, and implementing GIS programs within the Commonwealth of Kentucky.
DGI works with both state and local government, and serves as a liaison to
federal mapping agencies.

- The geologic maps, reports, and data files developed by the Division can be
used by individuals, educators, industry, businesses, and government.
Tennessee Federal GIS Data Server
Developed by the Tennessee Federal GIS Users Group and
the supported by the Tennessee Geographic Information Council (TNGIC), this
server distributes spatial data layers that are shared among Federal, State,
and local GIS facilities in Tennessee.
National Elevation Dataset (NED) has been developed by merging the
highest-resolution, best quality elevation data available across the United
States into a seamless raster format. NED is the result of the maturation of the
USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the
conterminous US and 1:63,360-scale DEM data for Alaska. The dataset provides
seamless coverage of the United States, HI, AK, and the island territories. NED
has a consistent projection (Geographic), resolution (1 arc second), and
elevation units (meters). The horizontal datum is NAD83, except for AK, which is
NAD27. The vertical datum is NAVD88, except for AK, which is NAVD29. NED is a
living dataset that is updated bimonthly to incorporate the "best available" DEM
data. As more 1/3 arc second (10m) data covers the US, then this will also be a
West Virginia DEP GIS Server
Locate mining permits, abandoned mine hazards, dump cleanup
projects, toxics release sites, and voluntary remediation sites.
West Virginia State GIS Technical Center
To provide focus, direction and leadership to users of
geographic information systems (GIS), digital mapping and remote sensing within
the State of West Virginia.
Virginia Coal Bed Mapping Project (CBMP)
The goal of the West Virginia Geological and Economic Survey's
Coal Bed Mapping Project (CBMP) is to create a Geographic Information System
(GIS)-based inventory of coal in the great state of West Virginia.
Among the map layers available to select and display are:
structural contours, elevation control points, mined and remaining coal areas,
geological discontinuities, total bed thickness, net coal thickness, percent
parting, and thickness control points for 42 different coal beds.
