Exciting milestone for our GREENTRAVEL team!!
We’ve officially wrapped up data collection for our VR cycling experiments—with an impressive 151 participants 🚴♀️
Juulia Lehtinen explains more 👉 blogs.helsinki.fi/digital-geog...
Now it’s time to dive into data analysis with fresh excitement!
Celebration in our #GREENTRAVEL project @digigeolab.bsky.social
#VR experiments now concluded!! 🚴🏻♀️🌲🌳 🥳
Two months, 151 participants, a lot of learning. Kudos to the incredible team Silviya Korpilo, Om Ravindran, Ashish Shete, Jussi Torkko, Sini Ruohomäki, Juulia Lehtinen and Mansi Garg 💎🤩
Mobility viewpoint needs to be recognized in urban greening policies! 🚴🌳🏙️
New #GREENTRAVEL paper out!
A perspective paper by Silviya Korpilo et al., published in Ambio, describes how people’s contact with urban nature often happens when moving through space.
Interested? Read the paper here 👇
The onset of spring in Helsinki always inspires and energizes us, as do the amazing researchers who come to visit us! We're delighted to introduce Eline Rega, a PhD researcher from KU Leuven in Belgium who visits us this April! 🤩

Are doing #research using #Flickr data? Are you aware of the drawbacks?
Check out this cool article where researchers critically assess the use of Flickr #SocialMedia data in research on #conservation and #recreation in #nature. Key insights for #NationalPark and #ProtectedArea management.
Distribution of the use of Flickr. Three heat maps that show globes roughly centered in Europe and Africa, South-East Asia and the Americas. Use is centered in Europe and North America, and urban areas.
🚨 NEW ARTICLE 🚨
How many photos are uploaded to Flickr? Where? By who? Why does any of it matter? We explore the rise and fall of #Flickr in this @digigeolab.bsky.social paper by yours truly, @vuoggis.bsky.social, Johanna Eklund, Anna Hausmann & @tuulitoivonen.bsky.social out now!

Over 2.2 million regional student mobility flows across Europe from 2014 to 2022, published as #OpenData in Scientific Data!
Do check out this cool new work on Erasmus+ student mobility from our very own @waeiski.bsky.social, @miladmzdh.bsky.social, Oula Inkeröinen, and @ollejarv.bsky.social!
Schematic of the workflow in the article. Leftmost panel shows a representation of the input data with high diversity in the types of place names resulting from typographical errors, character encoding errors, language-specific spellings and use of different scripts. The centre panel shows the general workflow from preprocessing to geocoding and finally to validation. The rightmost panel shows the spatially enriched Erasmus+ mobility data on a map with edge-bundled flows representing different intensities of student mobility across NUTS 3 regions in Europe.
🚨🌍 NEW ARTICLE 🌍🚨
We geocoded the #mobility of over 2 million #Erasmus students across #Europe from 2014 to 2022 with @miladmzdh.bsky.social, Oula Inkeröinen & @ollejarv.bsky.social.
