The interactive map of Ohio
Coal and
Industrial Minerals depicts the locations of mines and quarries that
are capable of producing coal, limestone, dolomite, sand and gravel,
salt, sandstone, conglomerate, clay, shale, gypsum, and peat. Some of
the locations of the mining operations depicted since 2006 are based on
Global Positioning System (GPS) coordinates obtained in the field by
Ohio Department of Natural Resources (ODNR), Division of Mineral
Resources Management (DMRM) mine inspectors. In 2009 ODNR undertook an
effort to depict the remaining mines in more accurate locations. The
mine locations reporting in the 2008 report were located based on
observations from high-resolution aerial photography obtained from the
Ohio Statewide Imagery Program (OSIP). OSIP imagery was taken
during 2006 and 2007 flights and delivered for public use from 2008
through 2009. A few sites remain that have not been located using the
highly accurate processes previously mentioned. These sites have been
located using DMRM
permit maps and should be considered approximate. The base map
includes county and township boundaries, highways, railroads, as well
as major rivers and lakes. |

SCREEN RESOLUTION This map is
optimized for high resolution screens. A resolution of 1024 by 768 or
higher is best because it offers a larger enough view of the main map.
You can gain more screen space by toggle the F11
key to hide/show toolbars while browsing in Internet Explorer. Another
approach is to increase the screen resolution of your monitor/video
card settings.

SCALE DEPENDENT LAYERS The layers in
this map are scale dependent. This means that a layer will only become
visible at a certain zoom level. This is used to help speed drawing of
the map and to avoid cluttering the map with excess information.

DISCLAIMER Some of
the locations of the mining operations depicted since 2006 are based on
Global Positioning System (GPS) coordinates obtained in the field by
ODNR Division of Mineral Resources Management (DMRM) mine inspectors.
Other sites were geo-located using Ohio Statewide Imagery
Program (OSIP) (2006–07)
imagery utilizing the imagery to adjust the
locations for higher accuracy than those mines that were located using
DMRM permit map spotting techniques. Neither
the Ohio Department of Natural Resources, nor any division thereof, nor
any of their employees, contractors, or subcontractors, make any
warranty, express or implied, nor assume any legal liability or
responsibility for the accuracy, completeness, or usefulness of this
product. Any use thereof for a purpose other than for which said
