SAPPHIRINE


SAPPHIRINE (Sensor-based Analysis of Pollution in the Philadelphia Region with Information on Neighborhoods and the Environment) is a Shiny application that integrates social and environmental geospatial data from the Greater Philadelphia Area. It provides interactive visualizations to help researchers generate hypotheses for neighborhood-level health studies in Philadelphia.

SAPPHIRINE consists of the following tabs:

  • NDVI: Landsat Normalized Difference Vegetation Index calculated using satellite imagery for assessing vegetation greenness
  • TRI: Toxic Release Inventory chemicals released into the air
  • ADI: Area Deprivation Index for assessing socioeconomic disadvantage in a region of interest
  • SVI: CDC/ATS Social Vulnerability Index for identifying and quantifying communities experiencing social vulnerability
  • L&I Violation: Asthma-related Licenses and Inspections Code Violations in reference to the Philadelphia Building Construction and Occupancy Code (Philadelphia County)
  • Crime: Crime incidents from the Philadelphia Police Department (Philadelphia County)
  • Traffic: Amounts of vehicle traffic that travel the section of roads (Philadelphia County)
  • EPA Air Quality: Air pollutant levels from the EPA's Air Quality System database
  • Satellite Air Quality: Satellite-derived air quality data (NO2 and PM2.5)

Data covers the Philadelphia-Camden-Wilmington statistical area, unless otherwise specified. To download the data sets for this application, please click [sapphirine_data]

We strive to ensure that the data presented is error-free, but we would not guarantee that it is spatially and temporally accurate.
