We wrote a small piece on our open #Erasmus #StudentMobility data for a Finnish GIS professional magazine, Positio, with @miladmzdh, Oula Inkeröinen and Olle Järv. It is in #Finnish though.
PhD position Geographic Information Visualization and Analysis (GIVA) “GeoNavLearn” with Prof. Sara I. Fabrikant
We've done it
Finally, there's a canonical paper on the #QGIS project, its history, workings, and challenges: https://www.sciencedirect.com/science/article/pii/S2666389925001138
Thanks to @timlinux and @mbernasocchi for joining me in trying to tell the QGIS story
And here's @martinfleis et al.'s new street network generalization tool:
Quite many from @digigeolab were at the #LBS2025 conference last week presenting our work on #Mobility #GIScience #Geography and #GeoAI, and we wrote a small blog post on it.
Following that is @tadusko presenting his work on the rise and fall of Flickr and use of its data in #GIScience at the #LBS2025 conference.
Key takeaway is that #Flickr is highly biased data produced in the Global North by a select few highly active users, but widely used in research because it is the only major social media platform that still allows data collection using its API. The question remains whether the data should be used.
Brilliant work all in all!
The second day of #LBS2025 conference is about to start, and so is the onslaught of presentations from @digigeolab members and alumni on topics like #mobility #BigData #GIScience #MachineLearning #NatureRecreation #Segregation #EcosystemServices #Geography
I have the dubious honor of the very last presentation of the day, acting as the firewall between the scientific program and the conference dinner. Let's see how many turn up
@grimalkina Next month’s #StateOfTheMapUS will have a healthy mix of the human and tech sides, both grassroots and institutional, that would be relevant to those in or adjacent to #GIScience. Our friends at @OpenStreetMapUS offer discounts for academic affiliation, and they just started raising funds to hopefully offer scholarships for affected government employees too. https://en.osm.town/@OpenStreetMapUS/114457256592594448
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 paper by yours truly, Vuokko Heikinheimo, @eklund_jo, Anna Hausmann & @tuuli – now out in the Journal of Outdoor Recreation and Tourism.

We geocoded the #mobility of over 2 million #Erasmus students across #Europe from 2014 to 2022 with @miladmzdh Oula Inkeröinen & Olle Järv. The data descriptor article is published in #ScientificData, and is an output from the #MobiTwin project.
A quick illustrative #map on the implications of using different types of centroids in regional #demography #mobility and #migration studies.
Think about what you are emphasizing.
By using population-weighted centroids, you can emphasize the population perspective in the analysis instead of the geometry, potentially improving your analysis considerably. The distance difference is stronger in sparsely populated and remote regions.
I have struggled with many IDEs with their lack of good integration of interactive #Python.
VSCode and its derivatives are nice, but they do not play ball with my workflow. I can get what I want to work only partially, and it is much slower than my current workflow. Running one line at a time in an interactive window is excruciating.
Isn't it common in #DataScience and #GIScience to have an interactive workflow with a lot of back and forth reiterations with multiple line executions?
Has any of my #GIS #GIScience #paikkatieto colleagues bought the Finnish #SeutuData dataset? It is the "sequel" to the OG #SeutuCD data from past years.
I am thinking about the costs and resolution of the data. The original SeutuCD had population count level on the level of buildings, which we're after as we're looking at a current transport hot topic in #Helsinki and wonder whether we should acquire the data. The description of the newer data does not contain this information.
Hey #geography community on #Mastodon!
The 19th Conference on Location Based Services (LBS) will be held in Espoo, Finland from May 7th to 9th, 2025.
There are several topics in the conference ranging from big data analysis, ubiquitous positioning and context modelling to location privacy and digital humanities.
The call for papers is open!

Hey, do you want to work in #research #science and have a knack for coordinating projects?
Become my colleague and come work at the @digigeolab at the University of Helsinki as a project coordinator.
Our research group is a talented and fun bunch of people doing research in #geography, #GIScience, #mobility, and #conservation.
Deadline for applications is next sunday, so apply fast if you're interested!

Excited to go to #MobileTartu to present the things we've been up to in @digigeolab when it comes to regional mobility.
I'm presenting our on-going work examining changes in long-distance commuting in Europe during 2012-2022 using big social media and Labour Force Survey data.
Still some figures need to be finalized, but I am looking forward to the conference. Anybody else from the fedi #geography #giscience and #geospatial community in #MobileTartu2024?
Wow! I received a copy of a book we wrote a chapter for with @tuomo and Hanna-Mari Pienimäki.
It's one thing to see one's own work published on a website, but another feeling when you can hold it in your hand.
If you're interested in #multilingualism #sociolinguistics #UrbanStudies and #LinguisticLandscapes check out this book. Relevant also for #UrbanGeography #HumanGeography #GIScience and #multimodality
The #OpenAccess book is available here: https://oa.finlit.fi/site/books/e/10.21435/sflin.24/
New paper with David Rey-Blanco, @pelayoarbues, and Fernando Lopez presents an open data product with real estate values for three major Spanish markets in 2018: Madrid (n = 94,815), Barcelona (n = 61,486), and Valencia (n = 33,622).
The dataset is available as an #Rstats #package here:
