This EnviroAtlas dataset represents the percentage of land area within each census block group in American Samoa, CNMI, and Guam that is classified as Canopy, Impervious Surface, and Vegetation using the 2022 NOAA Coastal Change Analysis Program (C-CAP) dataset. It also includes calculations of these landcover classes per capita (square meters per person) by block group based on 2020 United States Census data. Finally, ratios of canopy to impervious surface and vegetation to impervious surface were calculated by block group. Vegetation includes canopy and scrub/shrub landcover classes but does not include other types of green space. 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).
