I see only a grey rectangle and a hand cursor.

The map likely geolocated you somewhere without buildings (or maybe in the ocean) and where it is the middle of the night (so everything is in shadow).

Try this link which shows the shadows at the Space Needle in Seattle WA today at 5pm:

Or look at the shadows of the Alps at sunrise:

Hi there! My office window faces east and this morning, your map showed shade from the building across the street (correct), as well as shade from my building on the lawn below my window (incorrect).

Thanks for the reply. Do you have a tree or bush outside your window? I estimate where tree shadows fall but it's not super accurate. In the settings dialog you can toggle, "below canopy", "above canopy" or disable tree shadows altogether.

I've seen the setting, and I've seen that you suggest toggling it when tree shadows seem inaccurate, can you elaborate on what that setting does exactly?

I've wanted something like this - in Boulder the foothills cast a shadow on the town considerably earlier than sunset provided by weather apps. So in theory, this should be possible to figure out when a park will actually see a sunset. Nice work!

One of my favorite apps is PeakFinder, it shows local topography in an AR style UI. It also shows where and when the sun will set given the mountains around you! Well worth the few bucks.

"Top of canopy" - view from above like looking down from an airplane window. You won't see any shadows looking down on a forest because you only see sunlight landing on the top of the canopy. Most accurate.

"Below canopy" - what shadows would look like on the ground. If you're in a dense forest everything is in shadow because the trees obscure the sun. I guesstimate how big and where the below canopy shadows land. Any vegetation that's more than 2 meters tall, I place a shaded area beneath it. Not super accurate because it treats trees like cylinders instead of a sphere/triangle on top of a cylinder.

"No trees" - only building and terrain shadows are shown on the map.

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

Toggling to no canopy fixes it - palm trees cast little to no shade
