Landscape drawing is an important issue. I am not speaking only of the debate between the supporters of computer software and the defenders of drawing by hand. I am talking about the kind of drawing that results—although it does seem to me, without wanting to fight a rearguard action and reject useful technological advances, that it is difficult to entirely overlook work by hand. The drawing plays a role that is at once descriptive and analytical—it is an instrument for visibility that makes it possible to understand how a landscape is made. But at the same time, it plays a constructive role since, in revealing this role, it creates the very thing that it unveils. It is the responsibility of the landscape architect to extend his gesture toward a futuristic area that is his alone to understand but that, if it is really made visible, will be clear to everyone in the end.
