The Terrain Toolbox is a tool that you can open in the Editor, which contains useful tools to help ease Terrain workflows. It allows you to create new Terrain from preset settings or imported heightmaps, batch change Terrain settings on multiple Terrain tiles, and import/export splatmaps and heightmaps using the tools from the Toolbox.
To launch the Terrain Toolbox, select Window > Terrain > Terrain Toolbox.

The Toolbox window is a dockable window in the Editor, just like the Inspector. It comes with three tool wizards: Create New Terrain, Terrain Settings, and Terrain Utilities. It also includes the Terrain Visualization menu that lets you analyze the Terrain.
