Beach-surface and grain-size maps of Isbjørnhamna, Svalbard (2018-2024)

This dataset is related to the manuscript “Context-Aware Deep Learning Ensembles for Beach-Surface and Grain-Size Classification in Isbjørnhamna, Svalbard”. It contains 15 maps of beach-surface and 15 maps of grain-size classification at 1 m resolution for the Isbjørnhamna beach. The maps are based on an existing set of digital elevation models and orthomosaics at 0.05 m resolution created using DJI Phantom 4 Pro surveys and Structure-from-Motion photogrammetry over 2018-2024 (https://doi.org/10.5281/zenodo.19327624), grain size data collected in the field in 2022-2024 (https://doi.org/10.5281/zenodo.21128398) and a deep-learning classification model. The beach-surface classes include: 0. Snow 1. Dry sediment 2. Wet sediment 3. Water 4. Bedrock 5. Boulder 6. Driftwood 7. Algae 8. Ice 9. Anthropogenic In the grain-size set, classes 1 (Dry sediment) and 2 (Wet sediment) are re-classified to: 11. Fine 12. Medium 13. Coarse The other classes are the same as in the beach-surface classification.
