This dataset contains photogrammetrically generated orthomosaics of shoreline outcrops at Loviisa, South-East Finland. We used a drone to photograph the outcrops from a flight altitude of 20 m. We processed the photographs into the orthomosaics using Agisoft Photoscan software. We used up to 10 ground control points to accurately georeference the orthomosaics. The resulting orthomosaics have a ground sampling distance of 0.55 cm / pixel. Coordinate system ETRS:3067, ETRS-TM35FIN and the filetype is GeoTIFF. The photos were taken and processed as part of a Geological Survey of Finland project, KYT KARIKKO, with funding from Finnish National Nuclear Waste Management Fund (KYT) during the summer of 2019.
