Περίληψη

This paper presents an evaluation methodology of the visual value of various landforms. The term ‘visual value’ refers to the public preference of various forms of the Earth's relief. It is a figure which, even though it depends on various subjective factors, aims to quantify and to predict the preference of the public for each ground morphology. A questionnaire survey was undertaken using a sample of 221 persons in the broader Athens. The means used to demonstrate the various forms of reliefs are 32 perspective digital relief images. Following this, and in order to investigate the elements of the relief that affect its visual value, 20 quantitative indices were developed and examined so as to select the best ones. Linear prediction models of the visual value were investigated from the previous elements, through a regression process. The application of the proposed model in physical environment planning are many, such as the identification of the positions that offer the best or worst view for the spatial arrangement of various activities, the prediction of visual impact by arranging works that alter the relief of a region, etc.
