Map is an Art. I didn't know that until I finished mapping all details in Zone A, Phú Mỹ Hưng New City Area, in the Saigon South New Urban area of Ho Chi Minh City.
What fascinates me was the colourful rendering of various areas and items, such as residential zones, schools, rivers and parks. Well, after slow mapping for 2 years and intensive work for 3 days by everyone and me, it turns out to be a piece of art.
Btw, I also draw administrative boundaries to the subdivisions of the Zone A - Phu My Hung. This sounds weird because they are NOT administrative, but they do help proper addresses to render. Further, zone boundaries make it more convenient for users when searching for them in the search box.
Now I know that OPENmapping is not about drawing roads. It brings everything.
