[HOT] Overpass and schools in Mali

[Andrew Buck]

Yes, it is correct there should likely be residential areas nearby, 
maybe a few km for some of them.  My point was that simply doing an 
"inside" query is not enough.  I don't know that overpass is capable of 
returning schools that are *not* nearby residential areas, only inside.  
You can return schools that *are* nearby residential areas, or 
residential areas near schools, but as far as I know there is no way to 
query on the opposite.
