In order to perform the GPR investigation on the tumuli, an unconventional method of data acquisition was exploited, involving, consequently, some non-conventional data processing steps. Photogrammetric survey was also performed, and 3D digital models of the prehistoric tumuli were created. The investigations have revealed some anomalies under two out of three investigated tumuli, which were interpreted as prehistoric tombs.<\/jats:p>","DOI":"10.3390\/rs14051280","type":"journal-article","created":{"date-parts":[[2022,3,6]],"date-time":"2022-03-06T20:40:02Z","timestamp":1646599202000},"page":"1280","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Ground-Penetrating Radar and Photogrammetric Investigation on Prehistoric Tumuli at Parabita (Lecce, Italy) Performed with an Unconventional Use of the Position Markers"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3213-2879","authenticated-orcid":false,"given":"Raffaele","family":"Persico","sequence":"first","affiliation":[{"name":"Department of Engineering of the Environment, University Campus, University of Calabria, 87036 Rende, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0007-8612","authenticated-orcid":false,"given":"Emanuele","family":"Colica","sequence":"additional","affiliation":[{"name":"Department of Geoscience, University Campus, University of Malta, MSD 2080 Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tiziana","family":"Zappatore","sequence":"additional","affiliation":[{"name":"Department of Cultural Heritage, University of Salento, Via Dalmazio Birago 64, 73100 Lecce, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudio","family":"Giardino","sequence":"additional","affiliation":[{"name":"Department of Cultural Heritage, University of Salento, Via Dalmazio Birago 64, 73100 Lecce, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7429-4767","authenticated-orcid":false,"given":"Sebastiano","family":"D\u2019Amico","sequence":"additional","affiliation":[{"name":"Department of Geoscience, University Campus, University of Malta, MSD 2080 Msida, Malta"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Goodman, D., and Piro, S.
