Investigating CalEPA DAC data maps
The objective of the project is to build a comprehensive tool for users to understand the benefit of low carbon transportation policy on California’s environment and public health. The system enables the exploration of CES data (CalEnviroScreen 2.0) measurements for 25 environmental and health metrics at very granular geographic levels. In addition to CES metrics, the system enables users to explore correlations between population metrics, low-carbon fuel user data, and registered Flex Fuel and Diesel vehicles in the state. All variables are available at the census tract level, except for registered vehicles which are only at the zip code level. The dashboard allows analysis and plotting at all three granularities: census tract, zip code and county.
Low carbon fuels and health impact correlations
The tool enables two variables to be plotted at once. The first variable selected will be the background and plotted at the county level. The second variable will be overlaid and can be at any granularity level. The tool also looks at all possible correlations between variables and displays the top correlations based on selected filters. The tool can split correlations by counties and observe differences across counties.
