Ah! I think I see the difference. My concept of the "map" is something that
starts out blank and the prime objective is to fill it in. I suspect the
use of a term like "door" implies a map supplied from outside. In which case
I agree that an object based expression of the surroundings is far better than
a raster based one. Unless .. you have an algorithm which allows your robot
to determine that something is a door! In which case I want to know a lot
more about how you do that!
