Download .zipThis theme shows existing and planned sewer facility service areas for each municipality in the county in 1982. The areas were delineated on USGS Quadrangle maps by the Lima-Allen County Regional Planning Commission.

This coverage was digitized from a USGS quadrangle map base utilizing a run length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 ft. The measurement increment along these horizontal lines was one decafoot (10 feet). 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 the boundaries as originally drafted . Additional details on the digitizing process are available on request.

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

description: FEMA Framework Basemap datasets comprise six of the seven FGDC themes of geospatial data that are used by most GIS applications (Note: the seventh framework theme, orthographic imagery, is packaged in a separate NFIP Metadata Profile): cadastral, geodetic control, governmental unit, transportation, general structures, hydrography (water areas and lines). These data include an encoding of the geographic extent of the features and a minimal number of attributes needed to identify and describe the features.

Download .zipThis map was derived from the Allen County Soil Survey using prime farmland map units as provided by the ODNR, division of Soil and Water Conservation in combination with land use/ land cover interpreted by the Remote Sensing Unit of The Ohio Department of Natural Resources.

Prime farmland is usually defined as land best suited and available for producing food, feed, forage, fiber, and oilseed crops. It has the soil quality, growing season, and moisture supply needed to produce sustained high yields economically when treated and managed, including water management, according to modern farming methods.

Soils used in this analysis were digitized from the paper original soil survey sheets. These sheets were taped together to form an area covering each of the USGS 7.5 minute quadrangle maps in the county. The areas for each quadrangle were then digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). The quadrangle files were then merged into a county file which has subsequently been converted to Arc/Info format.

The user should bear in mind that this coverage is only an approximation of the soil survey and should not be used for site specific analysis.

Additional details of the digitizing process are available upon request.

Download .zipThis ground-water resources theme shows an estimate of sustainable yield available from the aquifers in the area. It was digitized from a paper county map with a scale of 1:62500.

Digitizing used run length encoding techniques, sampling along horizontal lines which represented the midline of cells with a height of 250 ft. The horizontal measurement increment along these lines was one decafoot (10 feet). Additional details of the digitizing process are available on request. The coverage was subsequently converted to an Arc/Info vector format.
