2017 Unmanned aerial system (UAS)-derived orthoimage mosaics and digital terrain models of NE distal lava flow margin, Holuhraun lava flow-field, Vatnajökull National Park, Iceland
Using Phantom 4 Pro imaging systems, aerial images were acquired over short section of the NE Holuhraun lava flow margin, adjacent interior and adjacent river systems. Images were initially geocoded using the device's onboard GPS. Final products were coregistered to more precise geocoded image...
