the definition of "hires" used in this application is "imagery is 
available at zoom level 14 or more". If you compare coverage areas 
linked to on the wiki page, you'll see that almost all of them 
correspond to that definition.

I'm aware that there might be levels of even greater detail, but that 
isn't implemented...
