This is great. I would love a way to simulate something like possible tree placement and how much shade that may generate over the years. There are some parts of my area that are, despite being cut out of a forest, devoid of trees but are supposed to be "outdoor shared spaces".
Full sun all day at a dog park in August, for example, just isn't a place I want to be.
Site maintainer here. There is a polygon drawing tool in the upper right corner of the map. You can use it to draw polygons on the map and assign them a height. The shadows will update instantly. You can use it to add buildings that are missing from the map, simulate a tree placement or even simulate cutting down a tree if you set the height to 0.
Very cool tool! It's generally accurate, but, there are spots showing shadows where there are no trees or anything at all to cast a shadow, and missing several spots where there are actually trees.
It's missing a 40' tall ash, a 40' tall maple, and all four 30' tall blue spruce. So they're not exactly small trees. Our septic field is showing as in shadow all day even though there are no trees near it. That shadow doesn't move at all like the rest so I'm not sure what it's detecting.
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.
Be sure to check out the different layers. In addition to the default which shows shade at a given moment, there are also options for hours of sun in given day, and an a UI to quickly show shade at any day/time of year.
Not specifically for eclipses but has been useful in finding places where the sun will be visible during the current eclipse since the eclipse will occur when the sun is quite low on the horizon.

This doesn't look particularly accurate, at least not relative to what I can see right now out my window.
Website creator/maintainer here. Happy to try and diagnose the error if you elaborate on what the discrepancy is (tree, building, hill, etc)...

It reminds me of this nice website for when you want to have a drink in the sun at a terrasse in Paris :D https://jveuxdusoleil.fr/#16/48.8551/2.3479
This is interesting. Have you used it to find a nice place to have a drink?
Yes, although those days I tend to prefer places in the shade, or inside with AC...
Does this handle eclipses
