A pedestrian route planner that compares the fastest route with the shadiest one, down to which side of the street to walk on.

Landing page captured for the 2026-09-15 issue.

Field notes

Lightshadow compares a fastest walking route with one optimized for shade at the user’s chosen departure time, including recommendations for which pavement side to use. Its model counts tree canopies from national LiDAR data and combines them with building heights from the Cadastre and street data from OpenStreetMap. The homepage identifies version 0.2.1 for Android, while noting that the route shadows are calculated estimates rather than measurements verified by walking.
