EnviroAtlas - Cleveland, OH - Meter-Scale Urban Land Cover (MULC) Data (2011 and 2013)

The Cleveland, OH EnviroAtlas Meter-scale Urban Land Cover (MULC) dataset comprises 2,737 km2 around the city of Cleveland and portions of surrounding counties. The area classified is based on the US Census Bureau's 2010 Urban Area for Cleveland, OH with a 1 km buffer added.

This area includes the majority of Cuyahoga and Lake Counties, and portions of Ashtabula, Geauga, Medina, Lorain, Portage and Summit Counties. These MULC data and maps were derived from LiDAR and 1-m pixel, four-band (red, green, blue, and near-infrared) leaf-on aerial photography acquired from the United States Department of Agriculture (USDA) National Agriculture Imagery Program (NAIP) in 2011 and 2013. The NAIP imagery was collected on several dates: August 12, 2011, September 03, 2011 and August 24, 2013. The data was comprised of 85% 2011 NAIP and 15% 2013 NAIP imagery. LiDAR data collected between March 18, 2006 and May 07, 2006 covered the entire study area. Six land cover classes were mapped: Water, Impervious Surfaces, Soil/Barren, Trees/Forest, Grass/Herbaceous Non-Woody Vegetation, and Wetlands (Woody and Emergent). Wetlands were copied from the best available existing wetlands data, which was a National Wetlands Inventory (NWI) layer from 2006. An analysis of 500 completely random and 81 stratified random photo-interpreted land cover reference points yielded an overall user's accuracy of 86.2% (see confusion matrix below). This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets). These data were created by two institutions and shared as part of an interagency agreement. The EPA created 57% of the classification while 43% was created by the University of Vermont Spatial Analysis Laboratory (SAL) under the direction of Jarlath O'Neil-Dunne as part of the United States Forest Service Urban Tree Canopy (UTC) assessment program.
