Geuneullo Navigator: How Seoul Students Are Saving Pedestrians from Record Heat with Shadow Calculation Algorithms
🇰🇷 It's getting hot in South Korea: a record of 42.5°C was recorded in Yangsan. Against the backdrop of this anomaly, a student from Seoul created the Geuneullo app, which plots routes not by distance, but by shade. 🌳📱 The algorithm calculates the sun's position and finds a path through shaded areas, turning shade from a convenience into a safety issue. Global warming makes such solutions relevant for all megacities in the world. #Geuneullo #SouthKorea #Technology #Heat2026
