This is really cool!

I've used an app called PhotoPills to plan landscape photo shoots in the past. It lets you drop a pin on a map and shows you the direction of sunlight at any given time of day.

Shade Map gives me so much more fidelity to play with. The pseudo-3D view with shadow rendering helps tremendously in previsualising a photo.

Does anyone know of code for simplified triangle geometry rendering of dem data? The color data from satellite images blows up storage cost but simplified geometry might be small enough to both be useful and pretty to look at.

Unfortunately it doesn’t seem to take into account terrain outside of the viewport. Try zooming into the tip of a mountain’s shadow during a “long shadows” time of day, once you zoom in enough that the mountain itself is out of viewport suddenly the area brightens.

Still, very cool visualization!

Hi HN. I've been learning WebGL and working on this project for about a year. I posted it previously when it worked in 2D and wanted to share it again because the 3D really makes the shade come to life. Most of the credit for the update due to migrating from Leaflet to Mapbox GL JS.

Hey. Very cool project. I have an idea. How about you add option to show buildings. That way, people can use this to detect shade on their rooftop solar panels and its stuff.

That would be something great

It's something I'm working towards. Right now you can see building shadows at street level zoom, but they're quite rough. Check out shadowmap.org, which is a project that does buildings well.

That was cool, it even shows the correct day for when I can hope to see the sun again from my house

That's incredible!

I'm looking for a house right now, that means I can check how much light it gets before even visiting it. Thanks!
