Google SketchUp for Site Design: A Guide to Modeling Site Plans, Terrain and Architecture
"This book adds valuable information about features not even mentioned in the "Missing Manual". This book allows you to create settings for your creations. SketchUp provides a "sandbox", an interface with tools that create organic geometry. In other words, you can push and pull "terrain" around to create hills and valleys. Then using other tools create streets, sidewalks, and planters. Place the buildings you've created on the terrain, and add vegetation around them - suddenly you have a world! This is a solid book, with good start-to-finish instructions in creating 3D objects, whether a bench or a cathedral." (eJournal of the Tucson Computer Society, December 2009)"This book illustrates a holistic approach to SketchUp, how it works and more importantly, what to do with it."
