“…Analysis with these data has provided insights on a wide variety of social phenomena and socio-spatial processes, including crisis situations. Examples include, e.g., analysis on population mobility and commuting ( Ahas et al., 2015 ; Järv et al., 2012 ), detecting functional economic regions ( Novak et al., 2013 ; OECD, 2020 ), the provision and accessibility to state services ( Järv et al., 2018 ), identifying migration flows ( Kamenjuk et al., 2017 ) and cross-border mobility ( Silm et al., 2020a ), analyzing (in)equity between population groups and spatial segregation ( Mooses et al., 2016 ; Shelton et al., 2015 ; Silm et al., 2018 ), supporting transport solutions ( Positium, 2019 ) and environmental management ( Heikinheimo et al., 2020 ; Poom et al., 2017 ), characterizing tourist behavior ( Campagna et al., 2015 ; Raun et al., 2016; Saluveer et al., 2020 ), or reflecting the lived experiences of people in case of disruptions ( Shelton et al., 2014 ). Much of this research is conducted in countries where access to mobile Big Data has been relatively easy.…”
