My friends and I used this for a camping party's solar panel's placement (for charging a battery). A large campsite with intermixed trees makes it hard to find the optimal spot on our own, but this map helped us keep the party going late into the night before we needed to turn on the generator.

And I for placing a permanent solar array - I live in a deep, steep valley with a broad range of topography, and it helped me find an optimal spot for year-round balance of shade.

Curious how it knows my location despite Safari not prompting and no location services indicator in my menu bar. (Mac, not iOS).

I'm not suggesting anything nefarious but it is odd.

Nice app/service though well done.

Based on the location I got it guesses the location from the IP. The accuracy of that varies wildly by country and ISP. The US is a place where it is usually accurate to the city level

FYI things too far out of the current viewport don't cast shadows, can be annoying for mountains/hills are sun down/set if you're not aware of it.

Aha thanks. I'm using a different computer and I mistakenly thought I had Private Relay switched on; it's not enabled on this machine. Turning it on gives expected results. Needed the IP reminder to figure that out!

Earlier quoted context omitted.

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 doe…

Sorry about that. The current tree estimate is done via computer vision but I am working on migrating to LiDAR backed data which should eliminate false positives. Just waiting for the TBs and TBs of data to download and then this Macbook M4 is going to make some heat...

Have you written up how you built it? I'd be curious.
