For manual delineation, we used optical Landsat-8 imagery. The dataset is composed of two parts. Firstly we provide ocean masks and frontal positions as Polygon or LineString Shapefiles respectively. Secondly, we provide 1220 input raster subsets (9 layers each) with their corresponding, manually delineated, segmentation masks. Input raster subsets have dimensions of 512 pixels by 512 pixels and are available in both png and georeferenced tif format. These machine learning ready raster subsets are optimized for training and validating artificial neural networks. 2024-01-01T00:00:00Z https://opara.zih.tu-dresden.de/xmlui/handle/123456789/6044 Terminus area change of 17 key glaciers of the Antarctic Peninsula from 2013 to 2023 derived from remote sensing and deep learning Loebel, Erik; Baumhoer, Celia A.; Dietz, Andreas; Scheinert, Mirko; Horwath, Martin Glacier terminus area changes are derived using the rectilinear box method applied to time series of glacier calving front locations. Terminus changes are provided in text file and image format. The following glaciers are included in this data record: Birley Glacier, Bleriot Glacier, Cayley Glacier, Crane Glacier, Dinsmore-Bombardier-Edgeworth Glacier system, Drygalski Glacier, Fleming Glacier, Hariot Glacier, Hektoria-Green-Evans Glacier system, Hugi Glacier, Jorum Glacier, Murphy Wilkinson Glacier, Prospect Glacier, Sjogren Glacier, Stringfellow Glacier, Trooz Glacier and Widdowson Glacier. 2023-01-01T00:00:00Z https://opara.zih.tu-dresden.de/xmlui/handle/123456789/6029 Historical Greenland glacier calving front locations from 1973 until 2013 Liebezeit, Charlotte; Loebel, Erik This product contains 170 Greenland glacier calving front positions from the following glaciers: Hagen Bræ, Helheim Glacier, Kangiata Nunaata Sermia, Nioghalvfjerdsbræ, Tracy Glacier and Zachariae Isstrøm. The glacier calving front positions have been manually derived from multispectral Landsat-8 imagery and are stored in an ESRI shapefile format using the WGS 84 / NSIDC Sea Ice Polar Stereographic North (EPSG:3413) Coordinate Reference System. Hagen Bræ covers the years 1985-2013 and Nioghalvfjerdsbræ between 1985-1994 on a nearly yearly basis. For Zachariae Isstrøm, calving fronts are featured every year between 1985-1993. With two calving fronts per year, except for 1984, Helheim Glacier involves the years 1979-1988. Irregular coverage with up to 3 calving front locations in one year show Kangiata Nunaata Sermia between 1978-2012 and Tracy Glacier covering the years 1973-2013. 2023-01-01T00:00:00Z https://opara.zih.tu-dresden.de/xmlui/handle/123456789/5992 Supplementary materials for the publication "Generative text-to-image diffusion for map creation based on geosocial media data."
