Abstract
In the framework of geosite management, specific targeted symbols for geomorphological legends are still lacking. Concerning geosites of geomorphological interest, geomorphological mapping requires targeted symbols in relation to goals and applications, either concerning geomorphic hazards and risk detection or the enhancement of resources, in particular those related to cultural heritage and, hence, geoheritage. A new methodology for mapping geo(morpho)heritage on geomorphological maps is presented in this paper. Nine iconic examples from the Italian landscape, selected in different morphogenetic and morphoclimatic contexts, are proposed to test the methodology in relation to point, polyline and polygon features. Moreover, guidelines for mapping are suggested according to the importance of the site and to the complexity of processes characterizing each case study.
Highlights
Geoheritage mapping is a quite recent research topic (e.g., [1,2,3,4]), and there are few examples especially addressed to land planning (e.g., [5])
The Italian Association of Physical Geography and Geomorphology (AIGeo), in collaboration with ISPRA (Italian Institute for Environmental Protection and Research) and the National Council of Geologists, has reviewed the official Italian geomorphological legend with the aims to: (i) create a legend widely applicable for applied purposes and suitable for scale comprised between 1:10,000 and 1:50,000; (ii) develop a multiscale objectoriented mapping model for being reproduced in GIS environments; and (iii) revise and update graphical symbols, after the first issue of the legend in 1994, due to the great progress made in Geomorphology in terms of new knowledge on geomorphological processes and landforms
Starting from this premise and depicting the state of the art regarding geoheritage mapping, this paper aims to: (i) propose a targeted legend and related symbols for detailed geomorphological mapping of those landforms that have been classified as geosites; (ii) test the proposed legend within different geological and geomorphological contexts; (iii) test the proposed legend and related symbols at a different scale; and (iv) elaborate guidelines for mapping geosites and integrating the new symbols within geomorphological legends in the specific case for the Italian territory
