Add CalEnviroScreen Example #2

Open daltare opened 11 months ago

daltare commented 11 months ago

Add example code showing how to estimate CalEnviroScreen 4.0 scores for water system boundaries. Data is available as a feature service or can be downloaded as a shapefile.

Estimation could be done using area weighted and/or population weighted estimation (see #1). May want to include examples of both, and compare results.

Potential approach: compute population weighted average scores, using interpolated population estimates :

  1. first compute interpolated populations by clipping ACS tracts to CES boundaries
  2. clip those boundaries to water systems and compute populations
  3. calculate population weighted averages (using areal-weighted populations from step 2)
