This data is highly useful for land and coastal mapping studies. \nIn particular, the light reflected from the Earth\u2019s surface (surface reflectance) is important for monitoring environmental resources \u2013 such as agricultural production and mining activities \u2013 over time. \nWe need to make accurate comparisons of imagery acquired at different times, seasons and geographic locations. However, inconsistencies can arise due to variations in atmospheric conditions, sun position, sensor view angle, surface slope and surface aspect. These need to be reduced or removed to ensure the data is consistent and can be compared over time.  \n&nbsp\nWHAT THIS PRODUCT OFFERS\n\nGA Landsat 8 OLI/TIRS Analysis Ready Data Collection 3 takes Landsat 8 imagery captured over the Australian continent and corrects for inconsistencies across land and coastal fringes. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. \n\nThe imagery is captured using the Operational Land Imager (OLI) and Thermal Infra-Red Scanner (TIRS) sensors aboard Landsat 8.\n\nThis product is a single, cohesive Analysis Ready Data (ARD) package, which allows you to analyse surface reflectance data as is, without the need to apply additional corrections. \n\nIt contains three sub-products that provide corrections or attribution information:\n\n     1) GA Landsat 8 OLI/TIRS NBAR Collection 3 \n     2) GA Landsat 8 OLI/TIRS NBART Collection 3\n     3) GA Landsat 8 OLI/TIRS OA Collection 3\n\nThe resolution is a 30 m grid based on the USGS Landsat Collection 1 archive.", "num_resources": 1, "num_tags": 9, "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/ga-landsat-8-oli-tirs-analysis-ready-data-collection-3", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]}", "state": "active", "temporal_coverage_from": "2019-04-09 00:00:00", "title": "GA Landsat 8 OLI/TIRS Analysis Ready Data Collection 3", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "d1539379-a559-4215-b1e4-f5aeb71e85ad"}, {"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": "2025-10-17T01:24:13.961319", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Link to data via NCI THREDDS", "format": "HTML", "hash": "", "id": "38f5ba80-129a-4032-93f0-a356e665d305", "last_modified": null, "metadata_modified": "2025-10-17T01:24:13.949030", "mimetype": null, "mimetype_inner": null, "name": "Link to data via NCI THREDDS", "package_id": "fb53d6c3-12ea-4f70-8422-c25b8286d858", "position": 0, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://thredds.nci.org.au/thredds/catalog/xu18/catalog.html", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "DEA", "id": "864f59b1-5d00-46a3-8859-154171952ea8", "name": "DEA", "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": "Earth observation", "id": "11587acc-2411-4ccc-aa83-9d9961c3e512", "name": "Earth observation", "state": "active", "vocabulary_id": null}, {"display_name": "Landsat", "id": "751697bf-bddf-4847-bb16-c00f4c8f50a6", "name": "Landsat", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}, {"display_name": "analysis ready data", "id": "b86a988f-1799-4efb-a92d-fe5d4e51eb60", "name": "analysis ready data", "state": "active", "vocabulary_id": null}, {"display_name": "observation attributes", "id": "75c21670-9024-4610-95a2-58bed05722d5", "name": "observation attributes", "state": "active", "vocabulary_id": null}, {"display_name": "satellite imagery", "id": "a129aa26-de6d-4279-8cfd-6a9f3e90444e", "name": "satellite imagery", "state": "active", "vocabulary_id": null}, {"display_name": "surface reflection", "id": "a174ad26-3383-4f50-a220-00b72049f7ef", "name": "surface reflection", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
