UAV-acquired orthomosaics of Loviisa shoreline outcrops

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 data is provided as GeoTIFF (.tif) and png files (pngs added 1.3.2023). Note that the KL2 tif original has been split into two png files (KL2_1 and KL2_2).

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.
