Download .zipMaps and data associated with oil-and-gas wells represent one of the largest datasets at the Ohio Department of Natural Resources. This GIS data layer contains all the locatable oil-and-gas wells in Ohio. The feature is derived from coordinates obtained from the Division of Oil and Gas Resources Management (DOGRM) oil and gas well database – Risk Based Data Management System (RBDMS). The RBDMS database has a long history and is a comprehensive collection of well data from historic pre-1980 paper well records (digitized by the Division of Geological Survey (DGS)) to post-1980 DOGRM database solutions.Since 1860, it is estimated that more than 267,000 oil-and-gas wells have been drilled in Ohio. The compressed file also includes a feature used to connect the surface location to the bottom location of a well that has been drilled directionally or horizontally. This feature is NOT the actual wellbore path, it is simply a graphical representation indicating the relationship between the two well points.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesDivision of Oil & Gas ResourcesOil and Gas Resources Management2045 Morse Road Bldg F-2Columbus, OH, 43229-6693Telephone: 614-265-6462Email: gis.support@dnr.ohio.gov Data Update Frequency: Every Saturday

Download .zipThis map combines slope, glacial geology, ground water availability, depth to bedrock, bedrock geology, and flooding potential to determine the limitations for sanitary landfill development. Categories are arranged in order of severity, with slope as the least limiting factor and flooding potential as the most limiting factor. This map is designed for general planning purpose and is not meant to take the place of detailed site investigations.

Observations and subtle shifts of vegetation communities in Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects. Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the eastern basin of Lake Erie.

Download .zipThis coverage represents an interpretation of land use and land cover types done from aerial photography. For an explanation of categories, see Ohio Land Use / Land Cover Classification System, Misc. Report 17 available upon request, or at www.dnr.state.oh.us/odnr/relm/reasanalysis/lumin.html. This publication is keyed to the four digit code found in the OCAPCODE item name code description.

This coverage was digitized from land use/ land cover interpretation data drafted onto USGS quadrangle maps utilizing a run length encoding technique, sampling along horizontal lines which represent the midline of cells with a height of 250 ft. The measurement increment along these lines was one decafoot (10 ft.) The quadrangle files were then merged into a county file which was subsequently converted to ARC/ INFO format.

The user should bear in mind that this coverage is only an approximation of land use/ land cover as drafted. Blue line copies of the original land use/land cover interpretation can be provided for a nominal charge. Additional details on the digitizing process are available on request.
