[Geowanking] Latitude/Longitude Polygons for world cities

[Christian Willmes]

Hi,

do you know about the vector map (vmap) data set [1]?
I know it about 20 years old and not really accurate but there are 
"metropolitan area" polygons in this data set, which may fit your needs.
You can get the data in shapefile format form here [2] in 1:1,000,000 
and not for the whole world but in 1:500,000 from here [3].

Download the 7z archived file(s) and extract it, the shape file you are 
looking for is the "pop-built-up-area-p.shp".

Cheers,
Christian
