Download .zipThe Ohio Wetlands Inventory is based on analysis of satellite data by Bruce R. Motsch and Gary M. Schaal and is intended solely as an indicator of wetland sites for which field review should be conducted. The satellite data reflect conditions during the specific year and season the data was acquired and all wetlands may not be indicated. Statistics generated from the inventory are intended solely as an approximation.

The Ohio Wetlands Inventory for Medina County was produced from April 1987 Landsat Thematic mapper data (cell size 30 meters by 30 meters) using ERDAS Image processing software. The raster data has been converted to ARC/INFO format and exported to an interchange file.

The data was originally georeferenced to UTM zone 17 coordinates NAD 27 and is also available in this coordinate system in ERDAS Imagine format.

The class of woods on hydric soils, wet meadow and farmed wetland fall on hydric soils when digital soils data is available for the county.

This coverage was digitized from a paper county map with a scale of 1:63360. 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.

Download .zipThis theme shows land use in 1979 as mapped by the Medina County Regional Planning Commission.

This coverage was digitized from land use information drafted onto USGS quadrangle maps using a 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 horizontal 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 the land use as drafted.

Download .zipA potentiometric surface map is a contour map that represents the top of the ground water surface in an aquifer. The contour lines illustrate the potentiometric surface much like the contour lines of a topographic map represent a visual model of the ground surface. A potentiometric surface map is very similar to a water table map in that both show the horizontal direction and gradient of ground water flow.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesDivision of Geological Survey2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6693Email: gis.support@dnr.ohio.gov

Download .zipThis coverage was extracted from the 1994 statewide land cover inventory of Ohio produced by Bruce R. Motsch and Gary M. Schaal of the Ohio Department of Natural Resources.

The land cover inventory for the State of Ohio was produced by the digital image processing of Landsat Thematic Mapper Data. The Thematic Mapper is a multi-spectral scanner that collects electromagnetic radiation reflected from the earth's surface in the visible, near infrared and mid-infrared wavelength bands. The resolution of the Thematic Mapper data is a 30 meter by 30 meter cell. The computer analysis of the data isolates unique spectral classes that relate to land cover characteristics.

The land cover inventory was produced from Thematic Mapper data acquired in September and October 1994. The data was classified into the general land cover categories of urban, agriculture/open urban areas, shrub/scrub, wooded, open water, non-forested wetlands and barren.

The land cover information reflects the conditions of the satellite data during the specific year and season the data was acquired. The Thematic Mapper data was processed using ERDAS image processing software. The data was originally created in raster format and georeferenced to Universal Transverse Mercator (UTM) zone 17 coordinates NAD27. The data can be combined with other georeferenced digital data layers.

The data is also available in its original ERDAS image format.

Download .zipThis map was derived from the Medina County Soil Survey using the Universal Soil Loss Equation to calculate estimated erosion rates from a soil with no vegetative cover such as from a construction site.

Factors combined by the universal soil loss equation include: rainfall factor, ersosion factor "K", and slope length and steepness factor. An average slope length and steepness factor for each soil mapping unit in the county was provided by John Hocker, District Conservationist for Medina County.

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 .zipThe criteria used to produce this analysis were based on Extension Service Bulletin 598. The following information was combined and is ranked in order of increasing severity or increasing difficulty of compensating for the limitation. ** 1) Texture ** 2) Permeability ** 3) Depth to bedrock ** 4) Flooding 5) Depth to seasonal high water table 6) Drainage 7) Proximity to surface water bodies 8) Slope 9) Land Use ** 10) pH (Soil Reaction) * Less critical water related factors- controllable by varying the application time ** pH is treated differently in the category descriptions because it is a severe limitation in most of the county. For all other factors, an area with a severe or moderate rating may have one or more less severe or moderate limtations associated with it. Please consult the publication "Land Capability Analysis in Delaware County" available from the ODNR, Division of Real Estate and Land Management for additional explanation on this type of analysis.
