In this community, forest is defined as Trees & Forest, and Woody Wetlands. Green space is defined as Trees & Forest, Grass & Herbaceous, Woody Wetlands, and Emergent Wetlands.Wetlands are defined as Woody Wetlands and Emergent Wetlands. This dataset also includes the area per capita for each block group for some land cover types. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. This dataset was produced the US EPA to support research and online mapping activities related to EnviroAtlas. This dataset was produced 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). The purpose of this dataset is to show the differences in land cover amounts between the block groups in the EnviroAtlas community boundary. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation. completed EnviroAtlas Coordinator U.S. Environmental Protection Agency, Office of Research and Development - Center for Public Health and Environmental Assessment CPHEA, EnviroAtlas Geospatial Data Owner 919 541-3832 109 T.W.

This lineage was generated by the FGDC CSDGM to 19139 transformation Begin with the Census Block Groups and the 1-Meter Land Cover Classification for the EnviroAtlas community. 2022-07-06T00:00:00 Convert the Block Groups to Raster snapped to the land cover, with 1 meter pixels. 2022-07-06T00:00:00 Tabulate the area of each land cover class within each block group. 2022-07-06T00:00:00 Rename VALUE_## fields to their abbreviated land cover class and "_M". If any of the LC classes were not evaluated in the community, add the field for that LC and calculate all records = 0. In this community, Shrubs, Agriculture, and Orchards were not evaluated. 2022-07-06T00:00:00 Use the block group tabulate area table to calculate block group land cover combinations: LandA_M = Impervious + Soil & Barren + Trees & Forest + Shrubs + Grass and Herbaceous + Agriculture + Orchards + Woody Wetlands + Emergent Wetlands; MFor_M = Trees & Forest + Woody Wetlands + Orchards; Green_M = Trees & Forest + Shrubs + Grass and Herbaceous + Agriculture + Orchards + Woody Wetlands + Emergent Wetlands; Ag_M = Agriculture + Orchards; Wet_M = Woody Wetlands + Emergent Wetlands. Note, if certain classes were not evaluated in this community, they will have 0 values in these fields. 2022-07-06T00:00:00 Calculate the percentage of the block group area that is forest, impervious, green space, wetlands, and agriculture using the total land area. Note, if certain classes were not evaluated in this community, they will have 0 values in these fields. 2022-07-06T00:00:00 Calculate the area per capita of impervious, forest, green space, and agriculture cover using SUM_POP10 from the block group shapefile. Note, if certain classes were not evaluated in this community, they will have 0 values in these fields. 2022-07-06T00:00:00 Calculate fields where SUMPOP10 = 0: Area Per Capita fields = -99999. 2022-07-06T00:00:00 Calculate fields Ag_M, Ag_P, and Ag_PC = -888888 to indicate that Agriculture was not evaluated in this community's land cover. 2022-07-06T00:00:00 Copy the table to the final geodatabase, removing extraneous fields. 2022-07-06T00:00:00 unknown 2029-02-13 This metadata was automatically generated from the FGDC Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2024-02-09T11:11:00 version of the FGDC CSDGM to ISO 19139 transform.
