This collection includes Digital Elevation Models (DEMs) and orthomosaics generated from each survey using Agisoft Metashape Pro software. In addition to the survey results, there are three key files: 1. READ_ME_Fagradalsfjall_2021_eruption_UAS_data.docx: A Read me file listing all file types and file names for the dataset. 2.Fagradalsfjall_2021_eruption_UAS_survey_processing_data.xlsx: A summary table providing camera and processing information for all UAS surveys included in the dataset 3. 2021_All_Reports_Metadata.zip: A folder containing all reports for the UAS surveys in this dataset. The UAS surveys were conducted by University of Arizona’s Lunar and Planetary Laboratory scientists and colleagues at the University of Iceland (Háskóli Íslands), Icelandic Institute of Natural History (Náttúrufræðistofnun Íslands), and National Land Survey of Iceland (Landmælingar Íslands). The survey data was processed at the University of Arizona. The surveys show lava flow emplacement, the growth of the lava flow field, and the growth of the cones surrounding multiple vents. This dataset includes surveys from March through August of 2021. --------------------------------------------- ## Files and Folders READ_ME_Fagradalsfjall_2021_eruption_UAS_data.docx: Read me file for dataset containing explanation of all file types and file names Fagradalsfjall_2021_eruption_UAS_survey_processing_data.xlsx: summary table of survey and processing information for all 15 UAS surveys included in the dataset 2021_All_Reports_Metadata.zip: folder contains all reports for the UAS surveys in this dataset.
