During the last two decades, the interest in the heritage values of geodiversity, mainly related to geology and geomorphology, has increased (Reynard and Brilha, 2018). Among the different methods used to analyse the geodiversity, geomorphological mapping can be considered as one of the main tools for the inventorying, assessment and valorisation of geoheritage sites.
In this study, we compared two legend systems to analyse the contribution of each to the representation and mapping of various geomorphological landscapes. The two legend systems considered are the UNIL (University of Lausanne) legend and the CGMED-Tunisia (Laboratoire de Cartographie Géomorphologique des Milieux, des Environnements et des Dynamiques) legend. Both were used to map four sectors: (i) the Sebkhet Oum Ez-Zessar Ramsar site on the Gulf of Gabes coastline and (ii) the Wadi K'hil watershed on the Dahar Plateau, both located in south-eastern Tunisia, (iii) the Ferpècle glacier forefield and (iv) the Sanetsch area, both located on either side of the Upper Rhone valley in the Western Swiss Alps.
In addition, the combination of the contributions of these two legends has made it possible to elaborate a geotouristic legend (Ghram Messedi et al., 2021) and, from this, to produce four geotouristic maps. These maps emphasise the geoheritage and geotouristic interests of Sebkhet Oum Ez-Zessar and Wadi K'hil, which fall within the perimeter of the UNESCO Dahar geopark project in Southeast Tunisia, as well as the importance of the Ferpècle glacier forefield geosite, part of which is listed in the federal inventory of alluvial areas of national importance illustrating rapid climate change, and the Sanetsch glacier-karst area listed in the inventory of Swiss geosites.
