EnviroAtlas -- Birmingham, Alabama -- Meter-Scale Urban Land Cover (MULC) Data (2011)

The Birmingham, AL EnviroAtlas Meter-scale Urban Land Cover (MULC) dataset comprises 2,778 km2 around the city of Birmingham and portions of surrounding counties. The area classified is based on the US Census Bureau's 2010 Urban Area for Birmingham, AL with a 1 km buffer added. This area includes the majority of Jefferson County and a large percentage of Shelby County, as well as very small portions of Bibb, Blount, Chilton, and St. Clair counties. These MULC data and maps were derived from 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) that were collected in summer 2011. LiDAR datasets collected in 2010, 2011 and 2013 were also used to create this MULC. Six land cover classes were mapped: Water, Impervious Surfaces, Soil/Barren, Tree/Forest, Grass/Herbaceous Non-Woody Vegetation, and Wetlands (Woody and Emergent). Wetlands were obtained from the best available existing wetlands data, which was a National Wetlands Inventory (NWI) layer. An analysis of 500 completely random and 95 stratified random photo-interpreted land cover reference points yielded an overall user's accuracy of 83.4% (MAX) and an overall fuzzy user's accuracy of 87.6% (RIGHT) (see confusion matrices 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).
