This book covers almost every aspect of landscape sketch and graphic. It is good for you if you want to learn hand sketch, it is also good for you if you want to create nice CAD drawings. Many of the tree /shrub symbols in both plan views and elevation views are nicely done, they can inspire you to create nice computer blocks for trees and shrubs for plans and sections and elevations.
It covers graphic language and design process, basic drafting, lettering (nowadays almost everyone can do nice hand lettering fonts with computer, but this book is still good for assisting you to select lettering fonts or create your custom fonts in computer), freehand drawings and conceptual diagrams, presentation plans, section-elevations, graphic symbols files for elevations and perspectives.
All the sketches, plans, sections, elevations and perspectives are nicely done. They can be good samples for landscape architecture students, garden design students, architects, landscape architects, urban planners, and seasoned designers.
