DATA LAYER CLASSIFICATION

THEME:	Ohio Wetlands Inventory - Erie County
THEME ID:	1270
CATEGORY:	Geologic/Soils; Hydrologic;
ABSTRACT:	The 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.

Landsat Thematic Mapper Data	N/A	4/10/87

THEME AUTHOR: Bruce R Motsch

PURPOSE:

This project was done in cooperation with the ODNR, Division of Wildlife and the US Department of Agriculture, Natural Resources Conservation Service to provide a statewide inventory of wetlands. The Ohio Wetland Inventory is useful in general planning and environmental analyses. The wetland areas shown do not necessarily meet the definition of a regulatory wetland.
