This is awesome, thanks for sharing this!
I am especially impressed with the “i didn’t write a single line of code” part, because I was expecting it to be janky or slow on mobile, but it feels blazing fast just zooming around different areas.
And it is very up to date too, as I found a building across the street from me that got finished only last year being present.
I found a nitpicky error though: in Brooklyn downtown, where Cadman Plaza Park is, your webite makes it looks like there is a large rectangular body of water there (e.g., a pool or a fountain). In reality, there is no water at all, it is just a concrete slab area.
The author had built something like this image viewer before and used an existing library to handle some of the rendering.
the classic "water/concrete" issue! There's probably a lot of those around the map - turns out, it's pretty hard to tell the difference between water and concrete/terrain in a lot of the satellite imagery that the image model was looking at to generate the pixel images!
