We've used this website for years for checking the sun in various potential homes and holiday rentals. It's a half decent approximation but it doesn't really have proper height data (I think it's using standard building classification from Open Street Map data?) so it's only a guide.
But it's pretty cool overall! And I'll keep it in mind as we're in the process of looking for a new home.
They should offer some other way to trial the full version.
The sample convinced me. $2 is a really small investment.
They could probably have a side-by-side comparison of somewhere famous like Central Park (I'm from UK, fwiw) showing the free vs paid data to give an idea of what one might get; I guess it varies by location how much detail is mapped though, and how recently.
I’m very happy with the results. It confirmed my guess that a specific section gets more light over the year even though there is a bit more shade in the mornings until late spring.
The premium map is really good for my neighborhood!
I wonder if it's image processing from Planet data or something. Shape from shadows (then back to shadows?)
Maybe working back from that could feedback how high the buildings might be.
