The main goal of landscape design is based on the development of functional, economic, ecologic and aesthetic solutions in accordance with the user expectations and natural and cultural characteristics of the design space. Landscape design, which is usually realized within a creative process, considerably subjective approaches and the designer’s projections, now is not only supported with computer aided draft and design technologies but also geographical information technologies which enable the performance of inclusive and objective criteria based spatial analyses and evaluations. Within this context, in this study, shortest paths in terms of accessing specific points and suitable locations for observation terraces with high scenic values and potential to provide aesthetic satisfaction were determined in Eskişehir Şehri Derya Park, using shortest route and visibility analysis capabilities of geographical information systems (GIS). Accordingly, routes on 15 different nodes, as well as 9 deck areas providing scenery observation opportunities over the reservoir were determined via GIS. As a result of this research, it is aimed to highlight the capabilities and the contributions that GIS technologies offer for achieving efficient and targeted results during spatial design studies as well as planning processes.
