  3. Public Health Metadata Layering Risk Assessment Weather, Water, Flora, Fauna, Geography Critical Infrastructure Demographics Environmental Disease Variables

  4. Dynamic Meta-Data Layering

  5. The Problem Identify Locations of High Risk Populations for Vaccine Campaigns

  6. Lake Chad Documented Settlements

  7. Lake Chad Identified Populations

  8. Challenge • Using ½ meter panchromatic Satellite Images • Image extraction of settlements • Manual • CDC • Multinational Geospatial Co-production Program • Develop an Automated Methodology to Correlate Infrared Signals from NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS) Satellite with Extracted Features From ½ Meter Satellite Imagery • Using Near-Infrared & Short wave Infrared to validate occupancy or use

  9. NOAA/NASA (VIIRS)

  10. “Stable lights” Temporary/Transient Lights Fig. 1 – Image from 06/11/13. White spots are locations where VIIRS detected an artificial light source. Fig. 2 – Image with “stable lights” overlaid from imagery taken from June – November 2013.

  11. Fig. 3 – IR signals overlaid with surface features. Note: most light sources align with road networks and established cities.
