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 Wetland Inventory for Erie 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. Digital soils data for Erie County was not available at the time of the project.

Original coverage data was converted from the .e00 file to a more standard ESRI shapefile(s) in November 2014.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesReal Estate & Land ManagementReal Estate and Lands Management2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6462Email: 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 .zipThese data were derived from multiple sources, one of which was the USGS DLG data which was captured at 1:24,000-scale. The accuracy for DLG data is ± 40 feet. Although the USGS does not claim legal responsibility for the accuracy of these data.These files were obtained from the GIS Support Center, Ohio Department of Administrative Services and were originally prepared by the Ohio State University Center for Mapping in cooperation with the United States Geological Survey with additional funding from several state agencies and other groups. These files were augmented in a few instances with hand digitizing where small missing line segments were found. Originally the Lake Erie shoreline and islands in Lake Erie were added from the Hydrography layer (hy). At the time, the quadrangles used varied over a wide rangle of years this line does not represent a particular water level and is for illustrative purposes only. For example there is a wide offset between the shoreline on the Metzger Marsh Quadrangle and that of the Oak Harbor Quadrangle. This distance is so large that no attempt was made to edgematch the two quadrangles. The line connecting the two shorelines represents the quadrangle boundary. For the purposes of this map Sandusky Bay and Muddy Creek Bay were included as a part of Lake Erie. The Lake Erie shoreline is not meant to represent any Lake Erie shoreline which may be used for regulatory puposes. This has since been modified to be more accurate and inline with the NOAA project that mapped the bathymetry of the Great Lakes. The boundaries were modified to better match these data. An updated boundary for Fairfield-Licking-Perry Counties within Buckeye Lake was included by digitizing the boundary from a more recently updated quadrangle map.

Conversion from the dlg format to ArcInfo was accomplished using ArcInfo software in conjuction with an AML program to adjust the quadrangles so that their corners fall on the exact coordinates of the quadrangle corners. Due to the way in wihich coordinates are stored in the dlg's there is some variation in the quadrangle corner coordinates.

Since 200; additional edits to these data were made in 2002 by ODNR staff through the creation of the Public Lands Survey digitization project.

Further edits were made in 2012 in conjunction with a BLM project to establish cadastral standards.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesOffice of Information TechnologyGIS Records2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6462Email: gis.support@dnr.ohio.gov
