Mobility data to support COVID19 analytics

  1. 1. MOBILITY DATA IN FIGHTING AND UNDERSTANDING THE COVID19 AND RELATED CRISIS TUULI TOIVONEN, OLLE JÄRV, ELIAS WILLBERG, TUOMAS VÄISÄNEN VUOKKO HEIKINHEIMO ET AL. TUULI TOIVONEN / DIGITAL GEOGRAPHY LABGeoforum seminar 7.5.2020
  2. 2. COMBATTING THE VIRUS IS NOT PHARMACEUTICAL, IT IS MOSTLY SPATIAL. Testing and tracing, Bans on large gatherings, Non-essential business and school and university closures, International and domestic mobility Restrictions and physical isolation, Total lockdowns of regions and countries TUULI TOIVONEN / DIGITAL GEOGRAPHY LAB https://advances.sciencemag.org/content/early/2020/04 /27/sciadv.abc0764

UNDERSTANDING THE CRISIS CALLS FOR DATA Environment: Climate Weather Land use … Health : Diagnosed cases Underlying health conditions Other health data … Socioeconomy: Age distribution Employment and businesses Other socioeconomic variables … Mobility: Global to local scale movement of people, encounters, activity spaces …
