In mapping applications, it is the introduction of a considerable amount of Ground Control Points (GCPs) that enables the final reconstruction of a real-scale framed model. Since the survey of GCPs generally requires the use of total stations or GNSS receivers in Real Time Kinematic (RTK), either with or without a Network approach (NRTK), this on-site operation is particularly time consuming. In addition, the lack of clearly image-recognizable points may force the use of artificial markers (signalised GCPs) whenever no features are naturally available in the field. This implies a real waste of time for the deployment of the targets, as well as for their recovery. Recently, aircrafts\u2019 manufacturers have integrated the on-board RTK capability on their UAVs. In such a way, the high precision GNSS system allows the 3D position detection of the camera at the time of each capture within few centimetres. In this work, we tested the DJI Phantom 4 RTK for the topographic survey of a coastal section in the Northern Adriatic Sea (Italy). The flights were performed flying at an 80\u2009m altitude to ensure a Ground Sample Distance (GSD) of about 2 centimetres. The site extended up to 2 kilometres longitudinally. The results confirm that the on-board RTK approach really speeds up the precise mapping of coastal regions and that a single GCP may be needed to make a reliable estimation of the focal length.\n                    <\/jats:p>","DOI":"10.5194\/isprs-archives-xlii-2-w13-625-2019","type":"journal-article","created":{"date-parts":[[2019,6,5]],"date-time":"2019-06-05T19:24:11Z","timestamp":1559762651000},"page":"625-630","source":"Crossref","is-referenced-by-count":52,"title":["USING DJI PHANTOM 4 RTK DRONE FOR TOPOGRAPHIC MAPPING OF COASTAL AREAS"],"prefix":"10.5194","volume":"XLII-2\/W13","author":[{"given":"Y.","family":"Taddia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Stecchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Pellegrinelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3145","published-online":{"date-parts":[[2019,6,4]]},"container-title":["The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/isprs-archives.copernicus.org\/articles\/XLII-2-W13\/625\/2019\/isprs-archives-XLII-2-W13-625-2019.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,4,3]],"date-time":"2023-04-03T19:10:26Z","timestamp":1680549026000},"score":1,"resource":{"primary":{"URL":"https:\/\/isprs-archives.copernicus.org\/articles\/XLII-2-W13\/625\/2019\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/isprs-archives-xlii-2-w13-625-2019","relation":{},"ISSN":["2194-9034"],"issn-type":[{"value":"2194-9034","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,6,4]]}}}
