views from distances

the internet doesn't have everything.

I'm working on my novel right now and trying to figure out how much detail of someone else's actions a character with 20/20 eyesight could see at the distance of a quarter mile.

So I went online to see if any random genius had posted photographs of what things look like at various distances: 100 feet, 100 yards, a mile, etc.

Couldn't find anything like that.

Does anyone know of such a resource ... or would anyone like to create such a resource? ;) Seems like a good project for a student studying landscape, land use or surveying.

Just a suggestions.
