This utility enables you to alter the randomly generated landscapes of Sim City and create some landscapes of your own. Facilities are also available to help you smooth out the edges between trees and land to create a more natural look. You can even create a random landscape by altering the size and number of tree groups, the curving of the river and so on. You can then load the finished landscape into the original game and build over it at will.

Nothing spectacular, and certainly not worth the asking price unless you really want every Sim program ever.
