Please briefly introduce your position and research topic at the Digital Geography Lab

Hi! My name is Kirsi Ylinen and I recently started as a Research Assistant in the MOBICON project (Mobile Big Data for Understanding People in Nature) at the Digital Geography Lab. Over the summer, I will be studying national park visitation using mobile phone data. My goal is to understand who the visitors are, but more importantly, who are not visiting the national parks.

In what kind of positions have you worked prior to joining the Digital Geography Lab?

During my MSc studies, I majored in geoinformatics and explored various interesting topics from urban planning to conservation geography. One of the most rewarding experiences of my university journey was working as an assistant teacher in different geography and geoinformatics courses. Additionally, I worked as a geoinformatics intern for the City of Helsinki, where I focused on ecological and green networks within the city.

Digital Geography Lab contributing to Geoinformatics Research Days 2024

On May 20 and 21, the Geoinformatics Research Days 2024 were hosted at Aalto University. It is a yearly conference initiated by the Finnish University Network for Geoinformatics (Fiuginet). This year’s edition featured researchers from various Finnish institutions working on geospatial topics, but also from abroad. Digital Geography Lab was represented with several contributions.

On Monday, PhD researcher Robert Klein presented his ongoing research on access to travel greenery in major European Cities. He highlighted how temporal variation should not be overlooked when assessing greenery exposure and that there is a trade-off between accessibility and availability of travel greenery in European Cities.

Tuesday started of with a keynote as part of the GeoSPA talk series, organized by our lecturer Kamyar Hasanzadeh. Kamyar invited Franz-Benjamin Mocnick from Paris-Lodron-University of Salzburg to share his work. In his thought-provoking talk, Franz illustrated how simple objects can turn into geographical information by representing places such as tourist attractions, cities, etc. Also, he explained that the communication and representation of places are so subjective and selective, that GIScience is not yet equipped with tools to capture these.

We were also pleased to have our “senior affiliate” Christoph Fink with us for a couple of days. He engaged in the panel discussion on the role of Geo-AI and possible future developments. He pointed out how AI has transformed the work with data in a way that enables researchers to handle immense amounts of data in an increasingly convenient and quick fashion.

Who are you and what is your role at your home university?

I am Mahtab, a research associate at the Technical University of Munich. I’m trained as an urban planner and designer and am currently researching the interactions of urban greenery with the comfort of walking and cycling in my PhD. You can find me on LinkedIn: https://www.linkedin.com/in/mahtab-bp/

Please briefly introduce your research topic.

At the Research Training Group Urban Green Infrastructure (RTG-UGI), we’re a group of researchers looking into various aspects of greenery in cities. We cover a range of topics such as health, tree mortality and growth modelling, ownership, governance, etc and I am looking at the mobility aspect of human-nature interactions. More precisely, I like to understand how urban greenery affects the everyday active mobility experience and how it contributes to a more comfortable daily trip on foot or by bike. In doing so, I have a qualitative approach as the topic requires. I use User Experience capturing methods to go inside people’s heads while walking or cycling and track the live experiences of Munich’s and Helsinki’s residents and the reasons behind their feelings of comfort or discomfort.

Big data, big changes: Project MOBICON in the Canary Islands for a workshop and presentations

The Canary Islands are a biodiversity, geodiversity and tourism hotspot, boasting one of the most visited national parks in Europe (Teide in Tenerife). Tourism is the backbone of the local economy, but the growing masses of visitors put an unsustainable strain on the islands’ beautiful nature.

A collage of six photos: three of them of workshops and lecture halls, three from nature.

The islands are also acutely impacted by climate change and other megatrends including aging of population in Europe or digitalisation changing work life. On top of the traditional tourists, the islands are now receiving masses of long-term visitors seeking warm wintering grounds on the islands.  

These factors make the Canary Islands an interesting study area for the MOBICON project, where we study changes in nature visitation and their impacts on biodiversity conservation as well as the applicability of mobile big data sources for extracting visitor information.  

We (team Mobicon: Aina, Matti, Tatu and Tuuli) visited the islands of Gran Canaria and Tenerife in March 2024 for establishing collaboration with local universities and to collect research data through stakeholder discussions. Some highlights of the trip below.

Changes in nature visitation and the potential of mobile big data for visitor monitoring – Report from an expert workshop out now!

Aina Brias Guinart introducing a workshop task to the participants.

The importance of natural areas for recreation and conservation alike is critical, yet we often don’t know how many people visit them and why. Such information is necessary for the management and development of natural areas, which is why research by our lab and others have considered mobile big data sources (think data from mobile phones, social media etc.) as a way to monitor outdoor recreation. Yet, translating scientific research into actionable information for management is not straightforward – is it even wise? What kind of information do managers of natural areas need? What sort of changes do they managers see, how do these affect their information needs, and what sort of larger trends drive these changes? 

Researchers in project Mobicon called together experts from Finnish nature organizations to reflect on these questions in September 2023. The aim of the workshop was to collect expert opinions related to the changes in the recreational use of nature, the monitoring needs related to the changing visitations, and to discuss the possibilities of various new data sources to meet managerial information needs. 

This workshop was the first of a series repeated in March 2024 in the Canary Islands. We have now released a report on the outcome of the Helsinki workshop. Check it out!

Who are you, and what is your role at your home university? 

My name is Xiao Cai, with a mixed academic background of urban planning, geoinformatics, and artificial intelligence (AI). I am currently doing a master’s program in Geoinformatics at the University of Tartu and expect to graduate in June this year.

Please introduce your research topic.

I am a big fan of urban informatics with a dedicated focus on AI approaches to uncovering urban mobility mechanisms using emerging geospatial big data. I was exposed to AI methodologies in 2022 by taking a machine learning course, but since then I have been highly motivated to leverage this powerful technique in urban mobility analyses. Up to now, I produced two papers in this regard – the one is to mine the hidden spatiotemporal characteristics of bike-sharing travel patterns using the k-means++ clustering algorithm, and the other one is to examine the non-linear associations of built environments with demographic-specific bike-sharing usage using the gradient boosting decision tree algorithm. In the near future, I would like to explore more possibilities of using AI methodologies (machine learning or neural networks) to understand the hidden patterns of population dynamics and potential causes. I am also looking forward to exploring more big mobility data (e.g., mobile phone data, smartcard data, e-scooter data, taxi data, etc.) as I am always excited when working with data.

Sharing our Lab Handbook

Research groups are the basic unit of research in many research fields in universities. At the University of Helsinki alone we have hundreds of research groups. Still, almost all groups invent their everyday practices from scratch.

A couple of weeks ago, we at Digital Geographic Lab organized again our yearly development day. There, we decided to share some of our practices publicly in the form of a lab handbook. So here comes:

Digital Geography Lab Handbook 2024 (note: updated 20.2.2024)

The practices have been developed over the years through suggestions of many past and present lab members.

We hope that sharing them will be useful to some other research labs/groups, or those just starting their own group ❤️
