Sci. Data"],"abstract":"<jats:p>Abstract. Fogo in the Cabo Verde archipelago off western Africa is one of the most prominent and active ocean island volcanoes on Earth, posing an important\nhazard both to local populations and at a regional level. The last eruption took place between 23\u00a0November 2014 and 8\u00a0February 2015 in the Ch\u00e3\ndas Caldeiras area at an elevation close to 1800\u2009ma.s.l. The eruptive episode gave origin to extensive lava flows that almost fully\ndestroyed the settlements of Bangaeira, Portela and Ilh\u00e9u de Losna. During December 2016 a survey of the Ch\u00e3 das Caldeiras area was\nconducted using a fixed-wing unmanned aerial vehicle (UAV) and real-time kinematic (RTK) global navigation satellite system (GNSS), with the objective of improving the terrain models\nand visible imagery derived from satellite platforms, from metric to decimetric resolution and accuracy. The main result is a very high resolution\nand quality 3D point cloud with a root mean square error of 0.08\u2009m in\u00a0X, 0.11\u2009m in\u00a0Y and 0.12\u2009m in\u00a0Z, which fully\ncovers the most recent lava flows. The survey comprises an area of 23.9\u2009km2 and used 2909 calibrated images with an average ground\nsampling distance of 7.2\u2009cm. The dense point cloud, digital surface models and orthomosaics with 25 and 10\u2009cm resolutions, a\n50\u2009cm spaced elevation contour shapefile, and a 3D texture mesh, as well as the full aerial survey dataset are provided. The delineation of the\n2014\/15 lava flows covers an area of 4.53\u2009km2, which is smaller but more accurate than the previous estimates from 4.8 to\n4.97\u2009km2. The difference in the calculated area, when compared to previously reported values, is due to a more detailed mapping of the\nflow geometry and to the exclusion of the areas corresponding to k\u012bpukas (outcrops surrounded by lava flows). Our study provides a very\nhigh resolution dataset of the areas affected by Fogo's latest eruption and is a case study supporting the advantageous use of UAV aerial\nphotography surveys in disaster-prone areas. This dataset provides accurate baseline data for future eruptions, allowing for different applications\nin Earth system sciences, such as hydrology, ecology and spatial modelling, as well as to planning. The dataset is available for download at\nhttps:\/\/doi.org\/10.5281\/zenodo.4718520 (Vieira et\u00a0al., 2021).<\/jats:p>","DOI":"10.5194\/essd-13-3179-2021","type":"journal-article","created":{"date-parts":[[2021,7,2]],"date-time":"2021-07-02T09:43:51Z","timestamp":1625219031000},"page":"3179-3201","source":"Crossref","is-referenced-by-count":14,"title":["UAV-based very high resolution point cloud, digital surface model and orthomosaic of the Ch\u00e3 das Caldeiras lava fields (Fogo, Cabo Verde)"],"prefix":"10.5194","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7611-3464","authenticated-orcid":false,"given":"Gon\u00e7alo","family":"Vieira","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0843-3658","authenticated-orcid":false,"given":"Carla","family":"Mora","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3199-7961","authenticated-orcid":false,"given":"Pedro","family":"Pina","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2338-5535","authenticated-orcid":false,"given":"Ricardo","family":"Ramalho","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9733-284X","authenticated-orcid":false,"given":"Rui","family":"Fernandes","sequence":"additional","affiliation":[]}],"member":"3145","published-online":{"date-parts":[[2021,7,2]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Bagnardi, M., Gonz\u00e1lez, P.
