It almost seems wrong at first glance, the shadow it casts is huge and it covers most of the city and far beyond. But it's probably my monkey brain that doesn't notice the gradual changes and isn't aware that where I am at that moment has less light than the surrounding areas.
What is " shade " according to this map? Do you know how much sunlight (lumens?) is lost? Or is this an extrapolation of the shape of the features? It looks like the edges are quite hard when they should be softer and have different levels of opacity? Especially when the sun is very low, because according to this image, the mountain casts a shadow all the way to the town north of the river, several miles away. I'm thinking out loud. https://shademap.app/#45.581,-73.4441,10.0642z,1641473011979...
I will make sure to pay better attention next time I'm in the city around that time.
How do the calculations go so smoothly? I mean for each pixel that is potentially in the shade there can be a many 'upstream' pixels in the direction that the light is coming from that could cause it to be shady if there was something high there. Doing that calculation for each pixel seems very intensive, or is it achieved in some other way?
I'm looking for a house right now, that means I can check how much light it gets before even visiting it. Thanks!
That would be something great
