Editor Basics
Before we do anything, let's take a look at the main elements of the editor.

The Topological Editor View is where you edit the terrain while
viewing it from above. More...
The Three Dimensional Editor View is where you edit the terrain while
viewing it in three dimensions. What you see is similar to what you will see when
you load the terrain up in SimCity. More...
The View Toolbar contains commands for changing how you look at your
terrain, such as zooming in and out and rotating the three-dimensional view.
More...
The Selection Toolbar allows you to choose the method of selection.
Everything in the map editor is done based on your selection, but we'll
come to that later. More...
The Transform Toolbar contains the different ways you can modify
your terrain, such as raising the height by one, lowering by one, etc.
