Mapping Air Population

Download to read offline

NACIS 2016 Presentation
Michael Peterson, University of Nebraska at Omaha
Paul Hunt, University of Nebraska at Omaha
Air population refers to the total number of people flying above the earth at any point in time. These people form a distinct and separate population from those still physically connected to earth. Real-time air population can be estimated by using an extensive network of ground aircraft sensors based on ADS-B (Automated Dependent Surveillance-Broadcast). An aircraft determines its position via GPS and broadcasts its position along with its identification, aircraft type, altitude and speed. Most commercial passenger aircraft are equipped with ADS-B transponders. The total number of passengers is calculated by multiplying the number of seats for each aircraft by the current seat occupancy rate. Using this method, the estimated air population is determined for the contiguous airspace over the United States. The air population is further divided by each state. In the interactive, real-time mapping system, maps are provided to show total state air population and the density of air population.

Mapping Air Population

  1. 1. Mapping Air Population & Mapping Real-Time Flight Data Michael P. Peterson & Paul Hunt & Konrad Weiß Geography / Geology University of Nebraska at Omaha
  2. 2. Air Population • Air population refers to the total number of people flying above the earth at any point in time. – a distinct and separate population from those still physically connected to earth • Ephemeral, like urban areas having a “high daytime population” – Air population exhibits similar daily patterns
  3. 3. Animated Atlas: Air Traffic over North America – 2007 • 75 animations, frame-based, 2003-2006 – Total flights, by airline, by aircraft, by city, by corridors, by region, by states – Condensing 24-hours into 30-seconds – Showed flight patterns • Pulsating hubs • Red-eye flights • Popcorn commuter traffic
  4. 4. LAX
  5. 5. JFK
  6. 6. United Airlines
  7. 7. United Airlines – pulsating hubs
  8. 8. “Popcorn” Commuter Flights
  9. 9. Data • Atlas based on FAA data • Flight tracking companies now collect data - FlightAware, - FlightRadar24, - PlaneFinder - Automatic Dependent Surveillance-Broadcast (ADS-B) - Raspberry Pi, dongle and filter $85 total
  10. 10. FlightAware PiAware Sites Urumqi, China
  11. 11. Air Population • Comment made to Paul: We should map the number of people flying above the US. • Pursued FAA connection – Needed dedicated hardware (router, server) – Special Connection (IPsec) – Installation of specialized data communication software • Designed for data security
  12. 12. Solution • Flight Tracking companies – All present maps of current traffic – Read data from their server using JavaScript • AJAX through proxy server • Organized by individual tile – Duplicated their data retrieval methods – Retrieving lat/long of flights, airline, aircraft, etc.
  13. 13. Evolving Implementation • Initial implementation was real-time – flight data was requested on page load • Later we decided we wanted more than just a snap shot – Began storing a day’s worth of data – required server side database – Now hourly requests stored (no more on-demand) • In the future we will use this for daily animations
  14. 14. Programmatic Methods • Mapping done with ESRI ArcGIS API for JavaScript – API performs spatial queries that allows features to be intersected based on geographic location – General Programmatic tasks • Flight data requested from database (AJAX) • Planes enhanced with population data • Planes (JSON objects) are added to map as points • Planes (and attributes) spatially aggregated to states
  15. 15. Live Demonstration
  16. 16. Map of Planes
  17. 17. Air Population by State
  18. 18. Ratio of Air to Ground Population
  19. 19. Air Population Density
  20. 20. Heatmap
  21. 21. 5 AM
  22. 22. 7 AM
  23. 23. 9 AM
  24. 24. 3 PM
  25. 25. 11 PM
  26. 26. 3 AM Ratio Air to Ground
  27. 27. 3 PM Ratio Air to Ground
