Shade Map
Points and comments are a snapshot, not live.
ShadeMap simulates sun shadows anywhere on Earth using 3D building and terrain data.
ShadeMap uses OpenStreetMap building data and computer vision to estimate tree locations, casting shadows in real-time for any location and time. It features an annual sunlight calculation, a polygon drawing tool to add or remove structures, and layers for hours of sun per day. The creator is migrating to LiDAR data to improve accuracy. A companion tool, Sunsit.io, exists for Berlin using digital surface models.
What commenters are saying
Overall, users find the tool useful for practical tasks like finding sunny terraces, placing solar panels, and checking eclipse visibility. Accuracy complaints center on tree shadows: computer-vision estimates miss or falsely detect trees, and the simplified model shades foliage as solid blocks. The creator responds actively, explaining the polygon tool for manual corrections and the planned LiDAR migration. A few comments note building height errors (possibly meters/feet confusion) and point to alternatives like Shadowmap.org, Jveuxdusoleil.fr, and PeakFinder.
