2018 Unmanned aerial system (UAS)-derived orthoimage mosaics and digital terrain models of the SE margin and NE distal lava flow margin, Holuhraun lava flow-field, Vatnajökull National Park, Iceland
Using the UX5-HP imaging system, aerial images were acquired over the SE and NE Holuhraun lava flow margin, adjacent interior and adjacent river systems. The images were captured in JPEG format using a Sony A7R digital camera with a 36 megapixel high-sensitivity CMOS sensor and a 15 mm focal length...
