EnviroAtlas - New Bedford, MA - One Meter Resolution Urban Land Cover Data (2010) Web Service
Dataset Identification:
Resource Abstract:
This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (https://www.epa.gov/enviroatlas).
The New Bedford, MA land cover 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 fuzzy accuracy of 92.3 percent. The area mapped is defined
by the US Census Bureau??s 2010 Urban Statistical Area for New Bedford, MA plus a 1 km buffer. Additional areas where imagery
was available but outside the 1 km boundary were also mapped but not included in the accuracy assessment. We expect the accuracy
of the areas outside of the 1 km boundary to be consistent with those within. 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).
