ÉVALUATION DE LA COMPATIBILITÉ VISUELLE DES SITES AVEC CERTAINS TYPES D'ACTIVITÉS

Evaluation of visual compatibility in order to facilitate the allocation of sites to spécifie activities This paper addresses the problem of elaborating a practical methodology to establish land use/ landscape compatibilities based on the aesthetic values of laymen and/or specialists. Such a procé­ dure can then be applied to the gênerai problem of rationalizing économie, environmental, social and aesthetic factors to allocate competing land use activities to development sites. Specifically, the paper considers the allocation of 5 possible land use activities to a set of 45 sites based on the consensus of aesthetic opinions of 84 respondents. In order to collect opinions on the rating of each site for each activity within a reasonable length of time, transparencies of the sites and activities were used. Data from thèse tests were organized in the form of préférence matrices for which measures of agreement and consistency were calculated. Relative ranking of sites for each activity was determined, based on the average percentage of times each site was preferred to each other site and the results of a multidimensional scaling algorithm. An attempt was then made to allocate sites to spécifie activities.
