However, our ability to observe Antarctica systematically at a continental scale is constrained by difficulties accessing, storing and pre-processing satellite imagery prior to analysis. Factors such as cloud masking, reflectivity, prolonged periods of darkness, changes in atmospheric water vapour, aerosols and signal scattering mean that corrections applied to satellite data in other regions and in existing global products aren\u2019t fully applicable to Antarctic conditions. To overcome these challenges, Geoscience Australia is developing Digital Earth Antarctica. This platform will improve access to corrected continental scale satellite data through use of Open Data Cube technology, providing open access to analysis ready time-series data that has been corrected and validated for Antarctic conditions. Optical data will initially include Landsat and Sentinel-2 collections, while Sentinel-1 will be pre-processed for access to synthetic aperture radar backscatter and interferometric data. Synthetic aperture radar (SAR) data over Antarctica overcomes the challenges of sustained observing during periods of cloudiness and darkness, and in Interferometric Wide swath mode can be used to detect changes in surface topography over time (InSAR).\nThis presentation will provide an overview of Digital Earth Antarctica\u2019s planned processing pipelines to produce analysis ready optical and SAR data and the wealth of opportunities that will be unlocked to observe, monitor and understand Antarctic systems.\nPresented at the 2024 Scientific Committee on Antarctic Research (SCAR) Open Science Conference, Chile", "num_resources": 2, "num_tags": 5, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/unlocking-antarctica-building-an-open-access-accessible-satellite-data-platform", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[-180.0, -90.0], [180.0, -90.0], [180.0, -50.0], [-180.0, -50.0], [-180.0, -90.0]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[-180.0, -90.0], [180.0, -90.0], [180.0, -50.0], [-180.0, -50.0], [-180.0, -90.0]]]}", "state": "active", "temporal_coverage_from": "2019-04-08 01:55:29", "title": "Unlocking Antarctica: Building an open access, accessible satellite data platform", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "0951ade7-8cb1-481f-8e0b-533b9b1398ca"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T20:06:49.095541", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Link to Conference Page", "format": "HTML", "hash": "", "id": "9dba3c3c-0ee1-431f-b68b-3a3dd010b328", "last_modified": null, "metadata_modified": "2025-10-16T20:06:49.087884", "mimetype": null, "mimetype_inner": null, "name": "Link to Conference Page", "package_id": "60d3b3c4-8d89-4beb-96a2-e0540ad27c4f", "position": 0, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://scar.org/events/osc/pucon-2024", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T20:06:49.095545", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Link to Abstract (page 115)", "format": "PDF", "hash": "", "id": "abfeaaa4-12ad-4527-832a-67e9a7f04a55", "last_modified": null, "metadata_modified": "2025-10-16T20:06:49.088018", "mimetype": null, "mimetype_inner": null, "name": "Link to Abstract (page 115)", "package_id": "60d3b3c4-8d89-4beb-96a2-e0540ad27c4f", "position": 1, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://www.scar2024.org/wp-content/uploads/2024/08/SCAR2024_Abstracts_web.pdf", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "ASTRONOMICAL AND SPACE SCIENCES", "id": "b9e60283-35f3-40f7-ac31-d6900443d1ce", "name": "ASTRONOMICAL AND SPACE SCIENCES", "state": "active", "vocabulary_id": null}, {"display_name": "EARTH SCIENCES", "id": "927af2a7-7457-45c2-bd55-10000fd09c14", "name": "EARTH SCIENCES", "state": "active", "vocabulary_id": null}, {"display_name": "ENVIRONMENTAL SCIENCE AND MANAGEMENT", "id": "25031166-8d21-4c0a-be85-55b0e695e781", "name": "ENVIRONMENTAL SCIENCE AND MANAGEMENT", "state": "active", "vocabulary_id": null}, {"display_name": "PHYSICAL SCIENCES", "id": "ff043c67-4e57-4df7-bf7f-b20f95eec07b", "name": "PHYSICAL SCIENCES", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
