The use of computer-aided tools is more and more widespread in the field of Landscape Architecture. As our activities at the National School of Higher Studies in Landscape Architecture (Ecole Nationale Supérieure de la Nature et du Paysage – ENSNP, Blois, France) are related to computer science, this computerization attracted our interest. Our goal is to propose approaches in order to develop Landscape Architecture methods and tools in this context. Many discussions with students and landscape architects who are teaching at our university led us to notice certain issues concerning the software applications used in Landscape Architecture. As presented in the next section, we are firstly interested in proposing an approach to help landscape architects during the analysis phase of a project. To efficiently communicate our solution to landscape architects, and especially to the students and the other teachers of our university, we chose an experimental method by implementing a prototype that includes our solution. The use of our prototype by landscape architects provides us with useful feedback. Then, we can improve our solution according to the nature of feedback. The participation of Landscape Architecture teachers and students to the experimentation is instructive and very motivating for all of us. This experimental method also brings new tools to the students.
