The block groups are from the US Census Bureau and are included/excluded based on EnviroAtlas criteria described in the procedure log. 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). The purpose of this dataset is to show the block groups included in the analysis of 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-Sustainable and Healthy Communities Research Program, EnviroAtlas Geospatial Data Owner (919) 541-3832 109 T.W.

Block groups were also included if they filled a hole in the community boundary. Block groups were excluded if they were islands or only touched the main portion of the community boundary at one corner. In this community, the boundary was extended to the county lines. A comprehensive list of metric creation steps is included in the Processing Steps.

This lineage was generated by the FGDC CSDGM to 19139 transformation Obtain 2010 Urban Areas Polygon File, 2000 Urban Areas Polygon File, 2010 Block Groups, and 2010 Blocks from the US Census Bureau along with associated population tables. 2012-03-01T00:00:00 Join the population tables with the associated blocks and block groups. 2012-03-01T00:00:00 Clip blocks to the 2010 Urban Area for the EnviroAtlas city. 2012-03-01T00:00:00 Summarize the block population by block group in a new table; urban areas are defined using blocks, so this will determine the amount of people within each block group who are within the defined urban area. 2012-03-01T00:00:00 Join the summarized block population table with the block groups polygon file. 2012-03-01T00:00:00 Calculate the percentage of the block group population that is within the urban area: [summarized block population by block group]/[total block group population] * 100 2012-03-01T00:00:00 Extract the block groups with greater than or equal to 50% of their population within the urban area to a new feature class. 2012-03-01T00:00:00 Append all block groups to the new feature class that will fill in any holes in the community boundary. 2012-03-01T00:00:00 Delete any block groups that only touch the main body of the community boundary at one corner or are islands set apart from the main body of the community boundary. 2012-03-01T00:00:00 Create a final version of the feature class for use in EnviroAtlas, removing all unnecessary attributes. 2017-09-11T00:00:00 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.
