4. 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

5. 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
…
9. but they are collected, owned and managed
by private companies with other interests than sharing it.
THERE IS A LOT OF BIG
(MOBILITY) DATA
OUT THERE
11. MOBILE NETWORK DATA
FROM TELEOPERATORS
Good representation of population,
promising possibilities
national in scale
12. 24H POPULATION
(see also Järv, Tenkanen, Salonen, Ahas & Toivonen 2018)
Relative distribution of people at
each hour of the day

Notas del editor
Ehdottaisin näitä kahta, jotka esityksessä näkyisi hyvin:
FinEstTwitter tiedosto: virolaisten liikkuminen Virossa (sininen) ja suomalaiset Suomessa (kelt) ja kahden maan rajaylitykset, jotka keskittyy Tal-Hel väliin. Hyvä esimerkki alueellisten hierarkioiden ja toiminta-alueiden tarkasteluun Twitter aineistolla löydettyjen liikkuvuuksien kautta.
Russians_visiting_FinEst tiedosto: venäläisten liikkumiset Viroon (vihreä) ja Suomeen (kelt) jSa lopuksi Suomen ja Viron sisällä ja kahden maan välinen liikkuminen (pinkki). Hyvä esimerkki (venäläisten) toiminta-alueiden/interaktion tarkasteluun matkailun/liiketoiminnan näkökulmasta.
