Making “Edges” Visible in Spatial Networks — New Paper Published in Transactions in GIS

Spatial networks play a central role in understanding human–environment interactions in cities. On 2025 GIS Day, our lab’s latest research paper is published in Transactions in GIS (TGIS), highlighting a long-standing challenge in this field: how to effectively incorporate spatial context carried by network edges.
