EnviroAtlas Estimated Intersection Density of Walkable Roads Web Service

Metadata Updated: April 10, 2019

This EnviroAtlas dataset estimates the intersection density of walkable roads within a 750 meter radius of any given 10 meter pixel in each EnviroAtlas community. Intersections are defined as any point where 3 or more roads meet and density is calculated using kernel density, where closer intersections are weighted higher than further intersections. Intersection density is highly correlated with walking for transportation. For specific information about each community's intersection density layer, consult their individual metadata records: Austin, TX (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B72177756-4DD2-4133-8E85-C4C46BFAEEE2%7D); Birmingham, AL (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Bc892e710-81cf-4ba3-a551-8024ffa7049f%7D); Baltimore, MD (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Ba950ce43-bbe0-44ba-805a-b413147e0092%7D); Brownsville, TX (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B990c2af4-2ac6-40f8-a7dc-cfea1479616b%7D); Chicago, IL (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Bb521f10b-4505-4867-ba2d-70719f667bbb%7D); Cleveland, OH (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Beb14c0ca-f26c-47eb-8198-02fba73784d6%7D); Des Moines, IA (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BA5C3A6F2-CA61-4E78-B57D-289E45B34EF5%7D); Durham, NC (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BAF794837-71B0-4B3F-AA95-996A9C19D8A6%7D); Fresno, CA (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B0D3E33D1-81C5-456E-A581-58049701ACED%7D); Green Bay, WI (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BFF478160-DCFF-453D-A7B7-F2C03DF1BC85%7D); Memphis, TN (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B9C5E1317-F07D-4CEF-935A-A494E0BE7A7F%7D); Minneapolis/St. Paul, MN (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Bea532fdb-df76-4c5b-afcf-2af27d5b5e10%7D); Milwaukee, WI (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B991BCB95-1624-4102-95D5-6B1E382F5C12%7D); New Bedford, MA (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B89E0CE0B-DAEE-430E-A8E4-C486B3FD803F%7D); New Haven, CT (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Bf39d7d21-064d-4498-9926-743d543bc8f0%7D); New York, NY (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BD70DE411-6B72-4806-9B40-04921B3EA230%7D); Phoenix, AZ (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BAFC1F0E1-EC52-41E4-8682-8885BED5A9B7%7D); Pittsburgh, PA (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BDA4B629D-3224-45AD-8C32-F27253634ED4%7D); Portland, ME (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B1CAE7A89-3562-4706-AA12-1E6220006179%7D); Paterson, NJ (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7BE1E6BB36-9E9E-41B8-BF44-33D56CCAE145%7D); Portland, OR (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B17F6E916-7805-40AD-85E1-61B63BBDE193%7D); Salt Lake City, UT (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7Bdbab21bf-487d-4116-bbfc-8a26109daf27%7D); Tampa, FL (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B356EC846-7733-4AA3-8E0D-83DFA5AA2C52%7D); Virginia Beach/Williamsburg, VA (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B3ff033c2-1d11-4dbf-aea7-f8bb8244bcc3%7D); and Woodbine, IA (https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B4E7173AD-5D8E-426A-9431-67FE34833523%7D). 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).
