[OSM-legal-talk] Attribution/Licensing for map derived from Standard OSM TIles

[Peter Cooper Jr.]

Thanks; that's a very helpful example. I knew I was overthinking it, and 
while yes none of this probably matters in practice for my map to my 
house I wanted to ensure I understood how it worked if I were to end up 
doing something more complicated one day.

Much appreciated,
Peter
