Digitaalinen itsenäisyys – Suomen seuraava kohtalonkysymys 🇫🇮
Suomi on riippuvainen yhdysvaltalaisista teknologiajäteistä. Riippuvuus ei lähitulevaisuudessa vähenny vaan syvenee.

Kuvakaappaus hankkeen loppuraportin kannesta, lukee "Viheralueiden käyttö Helsingissä". Kuvassa Töölönlahti kesällä.
Mikä on Helsingin sometetuin viheralue? Missä lenkkeillään, mistä otetaan lintukuvia? Missä käydään ympäri vuoden ja mitkä ovat kesäkohteita? Mm. näitä sivusimme yhteishankkeessamme massadatoista ja Helsingin viheralueiden käytöstä. Lisää tietoa blogistamme! blogs.helsinki.fi/digital-geog...
Together with Metsähallitus Parks and Wildlife Services we propose operationalizing the use of mobile big data for visitor monitoring and the management of outdoor recreation.

A map of Helsinki's urban core. It shows which areas are in the shade on a clear day in mid-June. Hietaranta beach and Töölönlahti bay are highlighted with photos, since they are have some of the sunniest spots on the map.
#30daymapchallenge 17: A new tool
Helsinki enjoyed a grand total of 12 minutes of sunshine in November (1.–13.11). No better time to remember that yes, the sun does still exists.
This map shows Helsinki's shadiest / sunniest places. New tool? #GRASSGIS solar modelling.

Our collaboration with Metsähallitus is moving ahead even more efficiently and with greater impact as we have signed MoU with Metsähallitus Parks & Wildlife Finland to deepen our research cooperation and streamline the two-way sharing of data and knowledge.

Do you ever use your mobile phone when spending time outdoors?
The answer is probably yes. In that case, you leave digital footprints about your visit. 🦶
How are these data useful for the sustainable management of nature areas?
👉 Watch our video for that and more! www.youtube.com/watch?v=_U5G...
We are very happy to congratulate our very own @ollejarv.bsky.social for receiving the Research Council of Finland Award on his work on #CrossBorder #Mobility #Transnationalism #Segregation and #NatureRecreation using #BigData such as #SocialMedia and #MobilePhone data.
Struggling with your PhD synopsis? ✍️ Try this - The reverse-order approach! 📚🧠
@tuulitoivonen.bsky.social and @digigeolab.bsky.social have been using the reverse-order approach to structure article-based PhD synopses — and it works!

Oikeutettu etu on 50-50: se joko on tai ei ole. Tällainen light-versio suostumuksesta on ikävän yleinen, mutta härski temppu varsinkin valtionyhtiöltä.
My dear fellow researchers in #America and elsewhere!
If you are in the midst of finding a new #academic home and securing new #research #funding the Research Council of Finland is preparing a large funding call to cover the period from 2026 to 2030.

Our new Associate Professor in #geography @geohelsinkiuni.bsky.social, Johanna Eklund 💎, giving her inaugural keynote talk at the Kumpula Faculty Day of @helsinki.fi 🤩
Johanna asks what actually works in #conservation and how this could be tested with #counterfactual approaches 💚
Gradu #maastopyöräily'stä Pallas-Ylläksellä, Pyhä-Luostossa ja UKK:ssa. Voisivatko urheilusovellusten massadatat auttaa kansallispuistojen suunnittelussa? Mikko Kangasmaa selvitti 👆
A cool new master's thesis on #mountainbiking in Finnish Lapland's #nationalparks. Mikko used #Strava and #Ridewithgps data to explore whether these sources accurately reflect where and when people like to bike. Could they even aid in managing these areas? 👇
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!

Uploads distributed per second of the minute and minutes of the hour. Only the first seconds and minutes diverge significantly, however, for the minutes, people like to upload on round figures (i.e., ten past, half past).
BONUS ✨
Random highlights from the dataset:
1) Median time between capturing a photo and uploading it to Flickr is one week.
2) People (or bots) like to upload on round figures (see pic)
3) Normalized by population, Iceland has the most Flickr users in our dataset.
Thank you to #Kone & Mai and Tor Nessling Foundations for supporting this work. A quantitative work like this would not be possible without a robust suite of FOSS tools. My thanks to the maintainers of #QGIS, #pandas, #geopandas, #duckdb, #dask, #statsmodels, #jupyter and many more!
We hope to help future research by sharing the aggregated datasets presented above as figures and processing codes to produce them: buff.ly/qoJeQn8
So, we argue that these trends and biases should be considered if opting for Flickr data. For example, if Flickr is used a proxy does a drop tell about the phenomena or the popularity of Flickr? All research that uses user-generated dataset opportunistically face similar questions.
Outcome of 100 repeated queries to the API. The a pattern not unlike the normal distribution.
(5) Finally, we tested the reliability of data acquisition from the platform and found that the API responds inconsistently to repeated queries.
Five 'chord diagrams'. They show connections between the origins and destinations of nature visitors at the level of continents. The majority of these visits are made in Europe and North America, especially as we get closer to present.
(4) All of this is reflected on who make posts from nature, or protected areas in this case. For example, Europeans and North Americans make about ¾ of the visits to African protected areas on Flickr.
Three line charts and a map. They show how the majority of use is in North America and Europe, although normalized by population, Oceania prevails. At the same time, the spatial extent that is covered by Flickr photos has dropped.
A global map of Flickr users normalized by population. Many in Northern Europe, Spain, UK, North America and Australia & NZ.
(3) Flickr is clearly a platform of the "Global North": it’s users and use are concentrated in Europe and North America. Over time, an even greater share of use is in Europe.
An area chart and a line chart. They show that few users posts the majority of geolocated pictures and that this imbalance has grown over time (expressed through Gini index).
(2) More of that remaining data is produced by the most active ‘super-users’ of Flickr – top 1 % of users uploaded about 1 / 3 of the photos!
