Shade Map: See How Sun Shadows Move Across Your City

Shade Map: See How Sun Shadows Move Across Your City

Shade Map is an interactive web app that simulates sun shadows on a 3D map of any location. It uses real terrain and building data to show how shadows shift throughout the day and year, helping users plan outdoor activities, assess solar panel placement, or simply explore the interplay of light and architecture. The tool is free to use and offers a unique perspective on urban environments.

Shade Map lets you visualize the sun's path and the shadows it casts in stunning 3D, anywhere on Earth.

    This is great. I would love a way to simulate something like possible tree placement and how much shade that may generate over the years. There are some parts of my area that are, despite being cut out of a forest, devoid of trees but are supposed to be "outdoor shared spaces".

    Full sun all day at a dog park in August, for example, just isn't a place I want to be.

    My friends and I used this for a camping party's solar panel's placement (for charging a battery). A large campsite with intermixed trees makes it hard to find the optimal spot on our own, but this map helped us keep the party going late into the night before we needed to turn on the generator.

    Ha! A friend and I had this idea ages ago when living in Austin. I actually have the domain “walkdarkly.com” registered for it, in case I ever got around to it. If somebody actually doing something with it wants the domain, I’m happy to talk about transferring it

    This doesn't look particularly accurate, at least not relative to what I can see right now out my window.
