EnviroAtlas - Sum of population near roads without tree buffer for the conterminous United States

Description

This EnviroAtlas dataset is a summary of total population near major roads without any tree buffer within 12-digit Hydrologic Units (HUC_12), based on the National Land Cover Database 2011 (NLCD 2011) percent tree canopy cover (TCC 2011) dataset. The metric is a measure of potential exposure to particulate matter from exhaust from traffic. Studies have shown that tree buffers can help improve air quality by filtering particulate matter for those living or working near roads. 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).
