Buying a house, outdoor shooting, installing solar panels and worried about pitfalls? You must save this god-tier website!

ShadeMap is a free web-based sun exposure and shadow simulation tool that requires no software installation and can be used directly in your browser. It simulates the shadow positions of mountains, buildings, and trees on any given date and time, displaying them in real-time on a map. Operation is similar to Google Maps. You can input an address or landmark to pinpoint a location, drag a timeline to adjust the date and time, and observe the shadow changes. The principle is to cast a ray from each map pixel towards the sun's direction; if the ray intersects with a building, mountain, or tree, that pixel is determined to be in shadow. Users can switch to 3D mode for a more立体 observation of terrain and building shadows. The 'Hours in the sun' and 'Annual sunlight' options in the layer menu allow you to view daily or annual cumulative sunlight hours. If a building lacks height data, it defaults to 3.1 meters, but you can also draw your own buildings and set their heights to simulate the shadow impact after future completion. Application scenarios include sun exposure analysis for architectural and urban planning, sunlight assessment for real estate and communities, solar potential analysis, and light planning for outdoor photography. For photographers, it helps predict the sun's position and shadow movement to avoid interference or utilize shadows for creative work. The data covers the globe, making it suitable for quick assessment of sunlight conditions.
