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 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!

The author had built something like this image viewer before and used an existing library to handle some of the rendering.
