Measuring Ivrea Landscape Attractiveness through GIS Multicriteria and Surveys

Basing on previous studies lead by Sjerp de Vries (2013) about measuring the attractiveness of Dutch landscapes, we investigated the link between landscape, attractiveness, appreciation applied on a small region of Piedmont (IT) on the east of Turin: the Morain Amphitheatre of Ivrea. Concerning the concept of attractiveness, we intend the presence of elements that can trigger an increase of interest. In order to measure the landscape attractiveness, we have developed a set of the elements (indicators) that make a landscape attractive and usable and (through surveys) submit them to a participate evaluation, thus giving each indicator the proper weight. Through a GIS-based method, rooted on open regional geographic data, we were able to use survey statistics for defining the proper weight of good and bad indicators in the ending map, that is called Appeal Capacity Map. Our method is aimed to support decision-making process in the framework of regional planning, contribute in the building strategies, and defining landscape units, building developing scenarios. Together the landscape attractiveness, we retain advantageous also the evaluation of the usability, considering the usability as the sum of the connectivity grade of mobility system and touristic offer (presence of hotels and farmhouses). Surveys includes the application of a PPGIS tool in a website called SightMap, that traces pictures of concentration shot by users, a major concentration of which means an identification of the landscape key-elements.
