Documenti digitali per la conoscenza integrata dei Geositi: l’esempio della Riserva Naturale delle Salse di Nirano

After elaborating a new geomorphological map and a Digital Terrain Model (DTM) by means of ArcView GIS, this study allowed an in-depth knowledge of the geomorphological processes taking place in the Natural Reserve of “Salse di Nirano” (Modena Apennines, Italy). In this area, where silt-clay soil types crop out, landforms and deposits resulting from the “endogenetic” activity of the mud volcanoes, due to running water, due to gravity and to anthropogenetic activities were recognised. Furthermore, the main elements of the hydrography and excursion itineraries within the Reserve were also shown both in the geomorphological map and in the DTM in order to provide the tourist with an easy interpretation of the surrounding landscape
