Europe transit map

Hello, and welcome to my personal website! On these pages, I share primarily work-related content and news. I am currently an Assistant Professor of Geoinformation Technology at the Department of Built Environment, Aalto University (Finland). I am also an adjunct professor (a Title of Docent) at the Faculty of Science, University of Helsinki, and an Honorary Research Fellow at the Centre for Advanced Spatial Analysis (CASA), University College London (UK).


At Aalto, I am a member of Geoinformatics Research group, and I lead the GIST Lab that advances research, teaching and open-source scientific software development around a variety of topics, such as:

  • GIScience
  • Spatial accessibility and mobility analysis related to sustainable urban development and mobility
  • Understanding human activities in natural and urban environments based on user-generated content, such as social media data
  • Sustainable use of water resources and the design of water resources policies
  • Cypersecurity around open spatial data

Software for advancing open science

I am part of the development team of the open source library r5py for multimodal spatial network analysis in Python; and I have created pyrosm, a small Python package to extract geospatial information from OpenStreetMap dump files. In addition, I have contributed to some of the core Python libraries for geospatial analysis and computation, such as geopandas and osmnx.

You can read more about these libraries from software -section.


I have authored and maintain a bunch of educational materials targeted for Python users including four openly available online courses and one text book. You can read more about these from teaching -section.


Me and my colleagues are working on various research and educational projects. You can read more about them from projects -section.


In case you are interested in collaborating, or if you would like to work with me and our team, do not hesitate to contact. You can contact me via email at henrikki.tenkanen [at] aalto.fi. You can also find me on Twitter as @tenkahen and on Mastodon as @htenkanen.
