Remote sensing plays an important role especially in spatially extended and not easily accessible sites for the purposes of preventive and rescue archaeology, landscape archaeology, and intervention planning. In this paper, we present a case study of a detailed topographic survey based on a light detection and ranging (LiDAR) sensor carried by an unmanned aerial vehicle (UAV; also known as drone). The high-resolution digital terrain model, obtained from the cloud of points automatically labeled as ground, was searched exhaustively by an expert operator looking for entrances to prehistoric hypogea. The study documents the usefulness of such a technique to reveal anthropogenic structures hidden by vegetation and perform fast topographic documentation of the ground surface.<\/jats:p>","DOI":"10.3390\/rs13030332","type":"journal-article","created":{"date-parts":[[2021,1,20]],"date-time":"2021-01-20T04:10:48Z","timestamp":1611115848000},"page":"332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Preliminary Archeological Site Survey by UAV-Borne Lidar: A Case Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3571-2353","authenticated-orcid":false,"given":"Marco","family":"Balsi","sequence":"first","affiliation":[{"name":"DIET, La Sapienza University of Rome, 00184 Rome, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6610-6498","authenticated-orcid":false,"given":"Salvatore","family":"Esposito","sequence":"additional","affiliation":[{"name":"Oben srl, 07100 Sassari, Italy"}]},{"given":"Paolo","family":"Fallavollita","sequence":"additional","affiliation":[{"name":"Oben srl, 07100 Sassari, Italy"}]},{"given":"Maria Grazia","family":"Melis","sequence":"additional","affiliation":[{"name":"DISSUF, University of Sassari, 07100 Sassari, Italy"}]},{"given":"Marco","family":"Milanese","sequence":"additional","affiliation":[{"name":"DISSUF, University of Sassari, 07100 Sassari, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Corsi, C., Slap\u0161ak, B., and Vermeulen, F.
