Infrastructure is fascinating to me, especially when it requires taking a step back to comprehend the sheer scale and complexity of it. The Open Infrastructure Map by Russ Garrett is a fantastic project which takes infrastructure data from OpenStreetMap and visualises it on an interactive map. I find this fascinating as it’s the kind of data you wouldn’t otherwise see on a map generated from OpenStreetMap data. I wonder what other hidden data exists!
