Interesting! I had never noticed the amount of shade created by the mountain in the middle of Montreal.
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.
"shade" means that there is no "direct" sunlight on that spot. Some object is in the way blocking the sun. If you were to go the a spot shaded on this map at the given time (and lay your eye at ground level), you should not see the sun (+/- 2 minutes or so because the suns disk is not a point as this model approximates)
