Road-Graph Neural Networks

Tags: gnn space syntax python

It’s been a while since my last post! Since then, I’ve completed a degree in Computing, with a slight focus towards data analytics modules. For my final year project (link to my paper), I investigated a potential synergy between Space Syntax - graph theory applied to road networks, and Graph Neural Networks, and in doing so developed a simple pipeline for machine learning on road networks using GNNs. This post serves as an introduction on how to set up such a pipeline in Python.

Precise Digital Elevation Models (DEMs) of Singapore are not so readily available online. In order to obtain one, it is necessary to sieve the island out from open source global DEMs. Hence, I thought that it would be useful to compare between those global DEMs and see which gives the best representation of Singapore. For easy comparison, I also made a Leaflet map that overlays the DEMs.
