Terrestrial laser scanning (TLS) is an increasingly important tool in the study of medium- to small-scale landforms in geomorphology. Two Leica TLS devices were used to create a detailed 3D model of Guerra Cave (Mt Berici, Vicenza, NE Italy). One device was the lightweight, compact, and mobile BLK2GO and the other was the BLK360, which is more precise but requires fixed topographic stations (tripod). Around 70 scans were used to survey the two branches of the 400-metre-long cave, including a vertical shaft of over 30 meters of depth. The 3D model of the cave facilitates the execution of morphometric measurements on the various cave environments. The TLS data enabled us to calculate the cave's volume and distinguish between different generations of cupolas, phreatic conduits, and basalt dykes. These observations enabled us to distinguish between different karstification processes and speleogenetic phases, highlighting the importance of primary hypogenic inception in the cave formation and following condensation-corrosion in modifying the cave volume.
La scansione laser terrestre (TLS) è uno strumento sempre più importante nello studio delle morfologie del terreno su scala medio-piccola in geomorfologia. Sono stati utilizzati due dispositivi TLS Leica per creare un modello 3D dettagliato della Grotta di Guerra (Monti Berici, Vicenza, Italia nord-orientale). Uno dei dispositivi era il BLK2GO, leggero, compatto e portatile, mentre l’altro era il BLK360, più preciso ma che richiede stazioni topografiche fisse (treppiede). Sono state effettuate circa 70 scansioni per rilevare i due rami della grotta, lunga 400 metri, compreso un pozzo verticale profondo oltre 30 metri. Il modello 3D della grotta facilita l’esecuzione di misurazioni morfometriche sui vari ambienti carsici. I dati TLS ci hanno permesso di calcolare il volume della grotta e di distinguere tra diverse generazioni di cupole, condotti freatici e dicchi basaltici. Queste osservazioni ci hanno permesso di distinguere tra i diversi processi di carsificazione e le diverse fasi speleogenetiche, mettendo in evidenza l’importanza della fase primaria di dissoluzione ipogenica e il ruolo successivo della condensazione-corrosione nell’allargamento dei condotti.

Abstract
Terrestrial laser scanning (TLS) is an increasingly important tool in the study of medium- to small-scale landforms in geomorphology. Two Leica TLS devices were used to create a detailed 3D model of Guerra Cave (Mt Berici, Vicenza, NE Italy). One device was the lightweight, compact, and mobile BLK2GO and the other was the BLK360, which is more precise but requires fixed topographic stations (tripod). Around 70 scans were used to survey the two branches of the 400-metre-long cave, including a vertical shaft of over 30 meters of depth. The 3D model of the cave facilitates the execution of morphometric measurements on the various cave environments. The TLS data enabled us to calculate the cave's volume and distinguish between different generations of cupolas, phreatic conduits, and basalt dykes. These observations enabled us to distinguish between different karstification processes and speleogenetic phases, highlighting the importance of primary hypogenic inception in the cave formation and following condensation-corrosion in modifying the cave volume.| File | Dimensione | Formato | |
