Usually in GIS apps this is known as the scale; and represented as the "scale
denominator". If you think of an exact picture as 1:1, and a half sized picture
as 1:2 (the scale denominator is 2) you can see that this number gets bigger as
you zoom out.
All the information on what area of the world to display is in the Viewport
now; you should be able to use that class; and the class ScaleUtils to
calculate the current map scale.
