Fogo in the Cape Verde archipelago off Western Africa is one of the most prominent and active ocean island volcanoes on Earth, posing an important hazard to both local populations and at a regional level. The last eruption took place between 23 November 2014 and 8 February 2015 in the Ch\u00e3 das Caldeiras area at an elevation close to 1,800\u2009m above sea level The eruptive episode gave origin to extensive lava flows that almost fully destroyed the settlements of Bangaeira, Portela and Ilh\u00e9u de Losna. In December 2016 a survey of the Ch\u00e3 das Caldeiras area was conducted using a fixed-wing unmanned aerial vehicle and RTK GNSS, with the objective of improving the mapping accuracy derived from satellite platforms. The main result is an ultra-high resolution 3D point cloud with a Root Mean Square Error of 0.08\u2009m in X, 0.11\u2009m in Y and 0.12\u2009m in Z, which provides unprecedented accuracy. The survey covers an area of 23.9\u2009km2 and used 2909 calibrated images with an average ground sampling distance of 7.2\u2009cm. A digital surface model and an orthomosaic with 25\u2009cm resolution are provided, together with elevation contours with an equidistance of 50\u2009cm and a 3D texture mesh for visualization purposes. The delineation of the 2014\u201315 lava flows shows an area of 4.53\u2009km2 by lava, which is smaller but more accurate than the previous estimates from 4.8 to 4.97\u2009km2. The difference in the calculated area, when compared to previously reported values, is due to a more detailed mapping of flow geometry and the exclusion of the areas corresponding to k\u012bpukas. Our study provides an ultra high-resolution dataset of the areas affected by Fogo's latest eruption \u2013 crucial for local planning \u2013 and provides a case study to determine the advantages of ultra high-resolution UAV surveys in disaster-prone areas.
