#30DayMapChallenge Day 4 #Hexagons comes from @haavardaagesen showing the locations of geotagged Tweets from cross-border movers in Europe during 2021–2022. The data is used in the #BORDERSPACE project lead by Olle Jarv to study cross-border mobility.

Study of the mobility is crucial in the #EU as the #Schengen agreement allows for free mobility between member states resulting in little official data on the characteristics of cross-border mobility.

#H3 #mobility #CrossBorder #research

Hooray! 🤩 We developed a tool to measure and map functional #BorderRegions from #CrossBorder #mobility of people w/ Michaela Söderholm, @haavardaagesen, Olle Järv, and myself.

Special thanks to @martinfleis for his help in spatial KDEs.

Special thanks also to Ate Poorthuis for excellent joint work on European cross-border mobility!

Today in #DigiGeoLab_AdventCalendar_2023🤩

meet Oleksandr, our 💎 social media and remote sensing data expert!
Currently, Oleksandr disentangles activity locations from various digital footprints to reveal cross-border mobilities of people in the #BORDERSPACE project 🌍

Today in #DigiGeoLab_AdventCalendar_2023 🤩

Meet Olle Järv our Academy Fellow studying cross-border mobility, transnational people and spaces \w big data in #BORDERSPACE and regional mobility flows in #MobiTwin projects

Olle’s critical thinking & vast knowledge make him a brilliant researcher but also a wonderful mentor!

It's so pleasant to relax #outdoors after a hard working day! Cross-border commuters in the Greater Region of #Luxembourg tweet outdoors quite frequently - work in progress from #BORDERSPACE project for Day 20 of #30DayMapChallenge
