This paper presents the results of the first attempt to assess, identify and quantify the residual number of shell craters of World War I currently present in the Vezzena/Luserna/Lavarone Plateau, areas of Millegrobbe, Bisele and Cima Campo (Province of Trento, Italy). Historical sources report the existence of several thousand artillery explosions: therefore, a field survey or a classic photo-interpretation would be labour-intensive and highly time-consuming. For this reason, a digital terrain model (DTM) of the test-site was processed using the Sky-view Factor algorithm and was analysed with an object-based approach, which implied: (1) multiresolution segmentation; (2) classification (main features considered size, shape and colour).

Abstract

This paper presents the results of the first attempt to assess, identify and quantify the residual number of shell craters of World War I currently present in the Vezzena/Luserna/Lavarone Plateau, areas of Millegrobbe, Bisele and Cima Campo (Province of Trento, Italy). Historical sources report the existence of several thousand artillery explosions: therefore, a field survey or a classic photo-interpretation would be labour-intensive and highly time-consuming. For this reason, a digital terrain model (DTM) of the test-site was processed using the Sky-view Factor algorithm and was analysed with an object-based approach, which implied: (1) multiresolution segmentation; (2) classification (main features considered size, shape and colour).
