EnviroAtlas -- New Bedford, Massachusetts -- Meter-Scale Urban Land Cover (MULC) Data (2010)

The New Bedford, MA Meter-Scale Urban Land Cover (MULC) data were generated from United States Department of Agriculture (USDA) National Agricultural Imagery Program (NAIP) four band (red, green, blue, and near infrared) aerial photography at 1 m spatial resolution. Imagery was collected in August of 2010. Seven land cover classes were mapped: water, impervious surfaces, soil and barren land, trees and forest, grass and herbaceous non-woody vegetation, woody wetlands and emergent wetlands. An accuracy assessment of 500 completely random and 45 stratified random points yielded an overall user's accuracy (MAX) of 92.3% and an overall fuzzy user's accuracy (RIGHT) of 95.1%. The area mapped is defined by the US Census Bureau's 2010 Urban Statistical Area for New Bedford, MA plus a 1 km buffer. 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.
