Full description
This dataset consists of topographic features across the East Antarctic coastal region, extending from 33°E to 168°E and from the coast inland to approximately 84°S in some areas.The features were digitised using ArcGIS Pro and were created within a topology to ensure the spatial integrity of the data. Line data include coastlines, ice fronts and grounding lines. Polygon data include continent features, islands, ice shelfs, ice tongues, icebergs, rocks and lakes.
The features were digitised at a scale of 1:25,000 using Sentinel2 imagery: earthexplorer.usgs.gov, 'Copernicus Sentinel data [2023]'. Note: Individual Sentinel 2 data source images are referenced in the data attribute tables with the exception of the coastline polygon dataset which was derived from the coastline line dataset.
Grounding lines were derived from ASAID_Grounding_line_continent_Sc_dep : Rignot, E., J. Mouginot, and B. Scheuchl. 2016.

The ASAID data were edited using ICESat2 data: Derived Grounding Zone for Antarctic Ice Shelves, United States Antarctic Program Data Center (USAP-DC) www.usap-dc.org ; http://www.usap-dc.org/view/dataset/609469 as well as Sentinel2 imagery and The Reference Elevation Model of Antarctica version 2 (REMA 2): Howat, I.

E., Noh, M.-J., and Morin, P., The Reference Elevation Model of Antarctica, The Cryosphere, 13, 665-674, https://doi.org/10.5194/tc-13-665-2019 , 2019 DEM(s) courtesy of the Polar Geospatial Center.
The Antarctic Iceberg Data were sourced from U.S.National Ice Centre (usicecenter.gov/Products/AntarcIcebergs) in CSV format. The CSV data used in this project is dated 3 Feb 2023. The point data were used to locate and digitise icebergs using Sentinel 2 imagery at a scale of 1:25000.
The 25K topographic features are stored in the Australian Antarctic Division Enterprise GIS and are available for download using the provided links.

PurposeThese features datasets were created in support of the 1:1 Million Topographic Map Series 2023 and the 1:1 Million Air Operations Planning Map (AOPM) series 2023 and to address deficiencies in the AAD's existing coastline dataset.
