It is nice to see a collaboration long in the works finally published.
We collaborated with #TalTech researchers Kofoworola Modupe Osunkoya and Jenni Partanen on a study of #UrbanVitality in #Tallinn #Estonia. We used a previously established framework to assess urban vitality and expanded it with information on dynamic linguistic diversity.
Essentially, dynamic perspectives are crucial in assessing urban vitality.

How can we embed innovation into our daily work? 🤔
At HeiGIT, we create space to experiment with new ideas and technologies, without immediate pressure to deliver results. This led to #Innovation Weeks, later evolving into Innovation Summer ☀️, giving teams more flexibility to explore their ideas.
Taking time to try something new, even if it might not succeed, has already led to successful tools like #MapSwipe and #SketchMapTool
Pretty cool!
My abstract got accepted to the World Planning Schools Congress! It has a different audience from my own field, so I am hoping for good discussion from fresh perspectives.
The conference is organized only every five years and this is its first time in Europe and as it is in town next summer, so it fits perfectly into my schedule. It will likely be the last time I'll yap about student #mobility for a while as new #GIScience projects are on my horizon!

📢 The next paper exploring the reproducibility of #GIScience publications is out!
I'm extremely grateful for the continued collaboration with @f_ostermann & Carlos Granell & others, and excited about the results. We collected evidence that the combination of reproducibility guidelines and reproducibility reviews can indeed improve the potential reproducibility of data/software-based research publications.
![Longitudinal assessment of research in GIScience domain shows a positive impact of reproducible research practices
Reproducibility is increasingly recognised as a cornerstone of rigorous science, prompting many publishers to require full documentation, data and software access, and archiving of study materials. Yet prior work shows that such practices, that are essential for communicating research transparently, remain comparatively low in the Geographic Information Science (GIScience) research community. To address this challenge, the AGILE conference series introduced the AGILE Reproducible Paper Guidelines for submissions in 2020. This study evaluates the effect of those guidelines and their implementation by a reproducibility committee. We investigate the evolution of the potential reproducibility of publications from the AGILE and the GIScience conference series, respectively, through a longitudinal analysis of full papers published before and after the introduction of the guidelines and corresponding review procedures. We assessed every full paper from both venues published between 2016 and 2024 using a rubric that classifies the availability of
data, computational methods, and results. Results indicate that the AGILE Guidelines and reproducibility reviews measurably improved the potential reproducibility of AGILE publications.

After several weeks of thinking and DEM preprocessing, I finally generated a complete geomorphons map for the part of Inhulets River basin (Ukraine).
It was far from easy — the original Copernicus GLO-30 DEM required careful cleaning, correction, and multi-step preparation before meaningful terrain forms could emerge.
What makes geomorphons truly valuable for me is how well they correspond to geochemical landscape types — eluvial, transeluvial, superaquatic, and subaquatic zones.
This overlap allows interpreting geomorphons as functional terrains with distinct element migration patterns, bridging geomorphology and environmental geochemistry.
All computations were done using R + SAGA GIS + QGIS, with the excellent Rsagacmd package for seamless tool integration.

📚 A short note for those who just joined my profile
Over the past few days, I’ve been sharing many posts — not for promotion, but to open parts of my long-term research archive.
During more than a decade of independent work, I’ve accumulated a huge amount of data, methods, and materials: from geochemical modeling and groundwater studies to urban greenness mapping and environmental visualization.
Many of these works were completed years ago but remained unpublished outside of narrow expert circles — so I’m gradually bringing them here, one by one, to make them visible and interconnected.
The pace will slow down soon 🙂 — what you’re seeing now is a process of unfolding a whole scientific story.

🏙️ The Hellish Trade Zones
(Ukrainian: “Торговельні пекельні зони”)
An older piece from 2017 — but still relevant today.
Using Landsat-8 thermal imagery, I explored how urban heat islands form in large commercial and industrial areas completely devoid of vegetation.
These “hellish trade zones” show surface temperatures exceeding 45–50 °C, while nearby shelterbelts and green spaces remain much cooler.
The visual storytelling approach — combining satellite data, maps, and simple explanations — helped raise public awareness about urban greening and environmental health in my city.
📍 Location: Kryvyi Rih, Ukraine
🛰️ Data: Landsat-8 (July 15, 2016), thermal band 10 + NDVI

🗺️ Making atlases better, one version at a time
Not everything works perfectly on the first try — sometimes the most obvious design ideas come late and suddenly! 🤣
Here’s one example: showing community boundaries so that people unfamiliar with cartography can at least find their own street.
In the second version (right), I added a subtle shading effect that keeps the map’s analytical context but visually highlights the selected community.
Each atlas is generated automatically in QGIS Report Designer — one atlas per city sector, with multiple communities.
That means this improvement wasn’t just “drawing a border manually,” but rather a data-driven programming and sorting task integrated into the atlas workflow.

🌊 Hydrological patterns in the Inhulets River Basin
I’m working on a large-scale study of the technogenic impact on the Inhulets River system (Ukraine).
The workflow combines R + SAGA GIS + QGIS for geomorphometric and hydrological analysis.
Over the past week, I’ve been refining digital elevation models and tracing surface runoff connectivity — not an easy task in a region reshaped by century of mining.
The map below shows one of the calmest and most “well-behaved” areas, far from the mining zone.
As for the drainage network over the mining areas… let’s just say it’s geological chaos down there 😄
