Stationary source lead emission data available from the EPA (TRI Explorer).

This is a combination of two datasets:
(1) LA County tree canopy data from TreePeople/University of Vermont
(2) LA County land cover data, 2014 imagery (Los Angeles Regional Imagery Acquisition Consortium)
Urban and rural tree canopy areas and percentages. Urban areas are defined as those census block groups whose centroids are within the Census’s “Urban Areas” shapefile.

Data includes cooling center addresses from LA County and City of LA websites for cooling centers, LA city recreation centers, and LA city year-round pools (2019 data).

Active/ inactive wells for all cities and unincorporated county with one or more active well sourced from Division of Oil, Gas, and Geothermal Resources, Oil & Gas Well Shapefile for California.

Downloaded annual reports of HAP metal emissions from TRI Explorer for LA County.
Cleaned data and totaled masses of point source and fugitive air emissions for each of the pollutants for each year.
Generated line graphs showing the emitted masses per year for the HAP metals included in the TRI report list.
Three separate plots were required to show the changes in emitted masses over time since they range over four orders of magnitude.
Created heat maps of median household income and created proportional marker symbols for each emitter address location (2017).

California Rapid Assessment Method (CRAM; an assessment method for monitoring the condition of wetlands) spatial data was sourced from EcoAtlas.

CPAD and SEA data was downloaded directly and classes were already identified within each data set.
The missing linkages comparison required dissolving the missing linkages data layer and the CPAD 2018 data layer, calculating the geometry in acres for both data sets, performing a union to combine the layers and the calculating the total area overlapped to determine percentages of linkage areas that are currently protected.
