There are a lot of techniques to create terrains and sites in Blender, like with the use of Grease Pencil and Surface Sketch. If you don’t remember the technique, just check back my article about terrain modeling with Blender 2.5. But, sometimes we may need a quick way to create terrains, and Google Earth is a resource to get terrain models. The trick is that we have to use Blender alongside with SketchUp to be able to import terrains from Google Earth. If you never did that before, there is a nice video that shows most of the process.
In the video below, you will learn how to import the terrain in SketchUp and create a file that Blender can import later.
