Examining Air Quality Data with BigData Analysis GIS Tools for Hadoop
Track: Big Data
Authors: Brett Gaines, Qi Dai
USEPA has maintained the Air Quality System (AQS) that contains air pollutant concentration data across the US. One challenge is how to analyze the vast amount of AQS data with multiple pollutants from many sites over 15+ years without spatial aggregation. This paper utilizes BigData tools and ESRI GIS Tools for Hadoop to analyze AQS data and reveals results that are often buried from aggregated analysis. It reviews AQS data with demographic and climate data over 15 years without aggregation.
