UAV imagery in Deception Island (Antarctica): PiMetAn Antarctic campaing 2020-2021

February-March 2021. XXXIV Spanish Antarctic Campaign. Deception Island (Shetland of South, Antarctica). Dataset: Orthomosaic flight images.This campaign report collects the orthomosaics generated with the images obtained from Unmanned Aerial Vehicles (UAV) during the XXXIV Spanish Antarctic Campaign in Deception Island (South Shetlands Islands, Antarctica) as part of the PiMetAn polar project (Ref RTI2018-098048-B-100). PiMetAn Project (http://pimetan.csic.es/) aims to evaluate the role of penguins in the biogeochemical cycles of trace elements in Antarctica and their effects on the Antarctic ecosystem. To achieve this, the Project includes, among many other activities, the use of different sensors boarded on UAVs to characterize and monitoring the regions of study. Thus, a total 42 UAV flights were carried out in different areas of Deception Island: Antarctic Spanish Base (BAE) Gabriel de Castilla, Vapour Col penguin colony, Baily Head penguin colony, Fumarole Bay, Murature’s region, Crater and Irizar lakes. The equipment used to collect the images were: these flights consists of the following UAVs and sensors: (1) Hexacopter (Condor, Dronetools ©) with three-bladed propellers with DJI6010 brushless type electric motor (130 kv) The drone could be equipped with the Micasense RedEdge-MX dual 10-band multispectral sensor, the FLIR Vue Pro R thermal camera, the Zenmuse Z30 video camera and the Alpha Sony 6000 RGB camera; (2) Quadcopter (Mavic 2 Pro, DJI ©) with integrated RGB sensor (Hasselblad Camera); and (3) Quadcopter (Phantom 4 Multispectral:P4M, DJI ©) with an integrated 5-band multispectral camera. After images were collected, orthomosaics was generated using the Pix4D Mapper software (Pix4D SA, Lausanne Switzerland).PiMetAn Project (Ref RTI2018-098048-B-100).Peer reviewe
