BorderRegion_KDE – A tool to capture cross-border regions from mobility

Authors: Michaela Söderholm & Olle Järv

One of the objectives of the BORDERSPACE project is to empirically capture functional border regions, and transnational spaces in general, from the perspective of people – their mobility and social interactions across country borders. Our first studies showed how novel big data sources can reveal cross-border mobilities of people (Järv et al. 2023), and how that enables to map functional cross-border regions (Aagesen et al. 2023).

To scale up our approach and focus on all functional border regions in Europe, we needed a tool to automate multiple border region calculations. Thus, we developed BorderRegion_KDE – a program to automatically calculate a geographical Kernel Density Estimation (KDE) polygons derived from cross-border mobility, and visualize them.

Read more from our project page: BORDERSPACE and get in contact! The project focuses on studying cross-border mobilities and interactions, transnational people, and functional transnational spaces. The novelty of the project stems from the use of novel big data sources to provide valuable insights for cross-border research and practice. The project is carried out at the Digital Geography Lab — an interdisciplinary research team focusing on spatial Big Data analytics for fair and sustainable societies at the University of Helsinki.

Join our special session at ECTQG’23 in September

Olle Järv (University of Helsinki) and Ate Poorthuis (KU Leuven) organize a special session focusing on how dynamic mobility flows form functioning systems like communities, urban networks and regions at the European Colloquium on Theoretical and Quantitative Geography 2023. The ECTQG’23 takes place 14.–17. September 2023 in Braga, Portugal.

Join us and submit your abstract HERE. Abstract deadline: 15th May 2023. We plan to organize a special issue in a peer-reviewed geographical journal in 2023 and look forward to your contribution on the scope, in addition to our ongoing research in BORDERSPACE project. See our session description, below:

Special Session “From dynamic mobility flows to functional systems: Communities, urban networks, and regions”

The analysis of functional systems through spatial interactions has been a long-standing interest in quantitative geography. While traditional approaches often focused on single cities or countries, limited themselves to specific kinds of mobility (e.g. commuting or migration), or a single point-in-time, new (big) data sources and computational methods have opened up new avenues. By not only providing new insights on temporal rhythms of functional systems, these systems can also be investigated at larger global and cross-country scales, and capture for more heterogeneous types of mobility (e.g. cross-border commuting, multilocal living, recreation and social networks). This can shed new light on, for example, border regions from different countries forming one functional system regarding peoples’ daily practices or the temporal rhythms of urban networks.

Join our session on cross-border regions at the RSA23 annual conference

Olle Järv together with colleagues from LISER (Luxembourg) organize a special session focusing on cross-border regions from the broad perspective of mobilities & social interactions of people at 2023 RSA Annual Conference Transforming Regions: Policies & Planning for People & Places. The #RSA23 takes place from 14.–17. June 2023 in Ljubljana, Slovenia.

Join us and submit your abstract HERE. Abstract deadline extended: Midnight 14th March 2023.

We plan to submit a special issue proposal to a well-established journal depending on the focus of presented studies after the conference. Read session description, below:

SS27: Understanding Cross-Border Regions through the Lens of Mobilities and Social Interactions of People

Session Organisers:

  • Olle Järv, University of Helsinki, Finland
  • Philippe Gerber, LISER, Luxembourg
  • Guillaume Drevon, LISER, Luxembourg

Session Description:

We live in a mobile world and cross country borders for various reasons – migration, tourism, work and education, and seeing family and friends. In addition to migration and tourism, cross-border practices are increasing due to the people whose daily lives are not confined to a fixed territory of one country, including cross-border commuters and people with multi-local living lifestyles between different countries (Gerber 2012; Carling et al. 2021; Järv et al., 2021). These recurring and frequent mobilities crossing country borders for work, shopping, services, and leisure not only affect individuals’ social connectedness and integration (e.g. social networks, well-being and place attachment) across borders, but also contribute to the (re)production of functional transnational spaces – border regions from different countries forming a functioning system.

Two new studies on revealing cross-border mobility and border regions

One of the goals of the BORDERSPACE project at the Digital Geography Lab is to examine whether and how social media data such as geo-located Twitter data can reveal cross-border mobility of people and provide new insights for understanding border regions. We demonstrate the feasibility of using Twitter data in two different recently published studies – the first study from the Greater Region of Luxembourg and the second study from the Nordic countries.

Conceptually, our approach was to make big data small and meaningful by: 1) using a bottom-up concept of activity space (e.g. Järv et al., 2014); 2) using mobility as a tool to capture individual activity spaces; and 3) contextualizing mobility from the border perspective.
