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.
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
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

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?
There are still four weeks left to submit your AGILE workshop proposal (extended deadline: January 10, 2025) and your full paper (extended deadline: January 15, 2025). We look forward to receiving your submissions!
