Summary
In 2016 and 2017 an archaeological survey project through LiDAR was carried out in the Barbanza peninsula (Galicia, northwest Spain) to identify and characterize all its megalithic monuments. This survey, that included both remote sensing and fieldwork, finished with a study sample of 119 mounds.The later work has been destined to research issues about the relation of these mounds with the mobility at different scales and their perception of the landscape. Inside this study, we raised the need of obtaining information about the morphological variables (surface, diameter, height and volume) of each mound. To do it, we elaborated a semiautomatic method that calculates these variables from the DTM using surface calculation tools of ArcGis.After selecting the megalithic monuments that were not excessively deformed we obtained their contours using an homogeneous criterion. Once delimited, we restored the removed parts of the mounds that showed inner alterations and then we calculated the rest of the variables inside each of the generated polygons.Obtaining these values has helped us to characterize the megalithic phenomenon in the peninsula faster than in the field. The results show significant differences of some of the monuments respect to the rest. Furthermore, standardizing these methods will help us to carry out similar studies in other regions of Galicia.
