This tutorial will guide you through the process of accessing and retrieving relevant environmental justice data, understanding how the EPA defines low-income disadvantaged communities (LIDACs) as per the Inflation Reduction Act, and connecting the LIDACs with EJScreen data using Geographic Information Systems (GIS). It will cover essential GIS techniques such as data integration, spatial analysis, and visualization. Upon completing this tutorial, you will have a comprehensive understanding of LIDACs, a GIS dataset that links EJScreen data to these communities, and valuable GIS skills that can be applied to environmental justice and policy analysis projects.
