DATA LAYER CLASSIFICATION

THEME:	1994 Land Cover - Erie County
THEME ID:	1269
CATEGORY:	LandUse/LandCover;
ABSTRACT:	This 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.

THEME AUTHOR: Bruce R Motsch

PURPOSE:

This coverage was created by the Ohio Department of Natural Resources (ODNR) for the National Aeronautics and Space Administration's Land Cover and Land Use Change Program, as part of the U.S. Global Change Research Program. ODNR will use this information in programs dealing with flooding and erosion, recreation, water resources, land use development, habitat, wetlands, natural areas, and fish and wildlife in the Lake Erie coastal region.

TABLE NAME: erlc94.pat

ITEM NAME: GRID-CODE

CODE	DESCRPTION
1	URBAN (open impervious surfaces: roads, buildings, parking lots and similar hard surface areas which are not obstructed from areal view by tree cover.) See 7. BARREN
2	AGRICULTURE/OPEN URBAN AREAS (cropland and pasture; parks, golf courses, lawns and similar grassy areas not obstructed from view by tree cover)
3	SHRUB/SCRUB (young, sparse, woody vegetation; typically areas of scattered young tree saplings)
4	WOODED (deciduous and coniferous)
5	OPEN WATER
6	NON FORESTED WETLANDS (includes wetlands identified from 1994 Thematic Mapper data as well as from the Ohio Wetlands Inventory)
7	BARREN (strip mines, quarries, sand and gravel pits, beaches) Many of the URBAN features identified in this inventory are constructed from materials obtained from the BARREN features. Because of this, there will on occasion be URBAN areas identified as BARREN as well as BARREN areas identified as URBAN.
