Road Orientations Map
Road Orientations Map The topic for day 8 of the #30DayMapChallenge is Urban . For this challenge I decided to go old-school and convert Vladimir Agafonkin's original Road Orientations from Mapbox to Maplibre. The original code analyzes street orientations and visualizes them as a polar histogram. I've just adapted Vladimir’s approach to work with MapLibre GL JS.
