The visual and aesthetic aspects of any object are defined by its color, texture, line, and form as well as compositional reference elements such as scale and spatial location in the three-dimensional context. Different methodologies have been developed to conduct visual assessments, based on analyses of the physical, aesthetic, and psychological attributes of the landscape. In this study, relationships between tourism buildings and the environment were analyzed across the perceived landscape and main shopping streets in terms of their color, texture, line and form, scale, and spatial location. Photographic-based questionnaires were administered in Kemer (near Antalya, Turkey) and Knokke (near Brugge, Belgium). In each location, 30 photographs taken of the coast and principal shopping streets were shown to 100 respondents of different ages, educational backgrounds, and nationalities. Two questions were then asked regarding the visual relationships in the photographs. Six questions regarding socioeconomic characteristics of the respondents were also asked. In both locations, the respondents preferred natural landscapes with few structures, and tourist resorts characterized by small, low-rise, and traditional buildings. The results of this study may provide suggestions for building and landscape architects about how to successfully integrate tourism buildings into the landscape 展开更多
