I'm having a lot of trouble creating an image of the city in my head and would like some help!

Any kind of image or graph is appreciated. Maps, artist renditions. Anything. Both for the city as a whole and the different locations within the city that Clarke describes.

But it must be accurate, or at least an attempt to be accurate (which is why I can't just use Google for this, since I lack the ability to distinguish between freestyle art and accurate ones).

Thanks!
