3D Landscape Design & Google Sketchup -- from the website: "I use a program called Sketchup for my 3D garden design. There is a free version and one that you must pay for, which has a few more features. However, most of the time I create landscape plans in plan view first. Plan view is a 2D design, where you view it as if you were above the property and looking down on everything."
This isn't really an educational resource; it's just a great site to see how SketchUp is being used by a professional landscape artist.
