What has cities, but no houses; forests, but no trees; and water, but no fish?

Common Wrong Answers
“A globe”
While a globe shows cities, forests, and water, it actually represents them in a three-dimensional form and has a physical surface, unlike a map which only represents these features symbolically.
“A computer game”
A computer game may have virtual cities, forests, and bodies of water, but it doesn't fit the criteria of having no houses, trees, or fish in the same symbolic way as a map does.
“The internet”
The internet consists of numerous data and resources related to cities, forests, and water, but it doesn't represent them visually in the way a map does, which is the main focus of the riddle.
