Oh right, so it's for areas that nobody has fully mapped yet, to give an 
interim indication of what it is? Or would it also serve a purpose once an 
area has been properly mapped with streets, basic amenities and landuse 
areas? As David Earl pointed out, if you have all the streets well tagged you 
already get an indication that it's urban, and if somebody has done the 
landuse areas you get data that can be used at all zoom levels just to 
show "this is a general urban area" as well as "this is a residential area 
with a little retail bit at the top".

If it's an interim thing then I suppose it might be handy, although I think we 
should really encourage people to map places properly.

Regards,
Tom
