A 2D slippy map that shows sun and shadow around the world.

Today’s sunset around Puget Sound: https://shademap.app/#47.89056,-122.66785,7z,1635813675213t

This is great! It’s been on my hacking project list for a couple years now. Glad to see it go. :)

I hike a lot. Figuring out exactly where & when sunset will hit is next to impossible in mountainous terrain.

Feature request, if you’ll entertain one: instead of a 1-bit sun vs shade, show a heatmap of sun angle. Think “interactive golden hour map” for photographers.

Nice! Was thinking it'd be cool to have a little tool that calculates the height of an object (tree, building, etc) given the length of its shadow and the time of day (GPS coords might also be necessary).

Seems like you've already performed most of the necessary calculations here.

Awesome site! I love moving around the sun like some kind of god.

It is very cool, will be using when planning morning or afternoon hikes in the mountains. Awesome job, thank you for sharing!

That's so cool! It's inaccurate for Manhattan though ;)

If you zoom in to city-block level you can see building shadows...

Oh wow, that's incredible. I didn't zoom in enough when I first looked, evidently!

This is awesome, I can definitely see landscape photographers using something like this in order to get the right timing for the shadows.

That’s awesome man I have no idea how you made that well done
