This EnviroAtlas dataset represents the percentage of land area within each census place in 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 place based on 2020 United States Census data. Finally, ratios of canopy to impervious surface and vegetation to impervious surface were calculated by place. Vegetation includes canopy and scrub/shrub classes, but does not include other types of green space.

    Datasets for other geographies were produced separately; metadata for these related datasets may be found here:
