Title: EnviroAtlas -- Cleveland, OH -- Meter-Scale Urban Land Cover (MULC) Data (2011 and 2013)
Abstract: 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, the University of Vermont, and the US Forest Service 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).
Purpose: The EnviroAtlas MULC provides spatially detailed foundational data for approximately 100 derived EnviroAtlas Community information layers. Some layers are developed at the native one meter MULC resolution and others by U.S. Census block group. While the EnviroAtlas National component is based on NLCD (National Land Cover Database, www.mrlc.gov) land cover data at 30 m spatial resolution (30x30 m pixel dimensions from the Landsat sensor), the EnviroAtlas Community component is based on MULC data at 900 times the spatial resolution. This permits analysis of common landscape features in the 1-10 m range which are unresolvable using 30 m NLCD pixels. Three such layers derived from MULC data are: Percent impervious area in 50m stream buffer; Value of asthma exacerbation cases avoided due to sulfur dioxide removed ($/yr); Percent of busy roadway bordered by < 25 percent tree buffer. Some of many possible applications of MULC include: Knowing the exact location and size of vegetated and non-vegetated spaces; Identifying highly impervious areas that would most benefit from additional trees and other vegetation to mitigate surface runoff and urban heat island effects; Measuring the width and character of urban riparian and street buffers; Locating potential wildlife corridors, gaps and linkages; Planning park development for maximum benefits. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation.
