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.

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.
