A HGL spatially defines areas of similar salt stores and pathways for salt mobilisation. The process of HGL determination relies on the integration of a number of factors: geology, soils, slope, regolith depth, and climate; an understanding of the differences in salinity development; and the impacts (land salinity/salt load/water electrical conductivity) in landscapes. Information sources such as soil maps, site characterisation, salinity site mapping, hydrogeological conditions and surface and groundwater data are combined to develop standard descriptions for each HGL unit.\r\n\r\nDerivative maps showing _overall salinity hazard_ and individual hazard due to salinity expressed as _land salinity, salt export (load)_ and _stream EC_ are available for most mapped areas, and are also viewable as custom layers in [eSPADE](http://www.environment.nsw.gov.au/espade2webapp).\r\n\r\nOverall salinity hazard uses a five class system (very low, low, moderate, high, very high). This helps the user identify and prioritise where salinity management actions may need to be targeted.\r\n\r\nHazard due to salt land, salt export and stream EC uses a three class system (low, moderate, high). Knowing which of these are of greater significance in a HGL unit helps the user decide on the types of management actions that may be applied.\r\n\r\nSpatial resolution varies between 1:50 000 and 1:250 000, depending on the resolution of the source data used to define the HGL boundaries.", "num_resources": 2, "num_tags": 3, "organization": {"id": "139dd472-a9c0-4063-8de9-3b9b5ff5f255", "name": "nsw-department-of-climate-change-energy-the-environment-and-water", "title": "NSW Department of Climate Change, Energy, the Environment and Water", "type": "organization", "description": "Ensuring a sustainable NSW through climate change and energy action, water management, environment and heritage conservation and protection.", "image_url": "2024-02-06-050442.862891imageupload", "created": "2024-02-06T16:04:42.881176", "is_organization": true, "approval_status": "approved", "state": "active"}, "owner_org": "139dd472-a9c0-4063-8de9-3b9b5ff5f255", "private": false, "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[139, -38], [139, -27], [155, -27], [155, -38], [139, -38]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[139, -38], [139, -27], [155, -27], [155, -38], [139, -38]]]}", "state": "active", "temporal_coverage_from": "2008-01-01", "title": "Hydrogeological Landscapes of New South Wales and the Australian Capital Territory", "type": "dataset", "unpublished": "false", "update_freq": "irregular", "url": null, "version": null, "extras": [{"key": "harvest_portal", "value": "SEED"}, {"key": "harvest_url", "value": "https://datasets.seed.nsw.gov.au/dataset/hydrogeological-landscapes-nsw-act"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-23T03:23:28.838708", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "format": "PDF", "hash": "", "id": "046ec368-4c3e-4dc5-a757-72cb496f6764", "last_modified": null, "metadata_modified": "2025-10-23T03:23:28.825106", "mimetype": null, "mimetype_inner": null, "name": "Data Quality Statement", "package_id": "e740ad88-dde7-4c3d-a9ae-2e3839ef20ca", "position": 0, "resource_type": null, "size": null, "state": "active", "tracking_summary": {"total": 17, "recent": 1}, "url": "https://datasets.seed.nsw.gov.au/dataset/hydrogeological-landscapes-nsw-act/resource/data_quality_report/pdf", "url_type": null}, {"cache_last_updated": null, "cache_url": null, "created": "2025-10-23T03:23:28.838714", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "format": "SPATIAL VIEWER", "hash": "", "id": "19a74e25-139c-4d19-97b4-47fc2753cd6f", "last_modified": null, "metadata_modified": "2025-10-23T03:23:28.825295", "mimetype": null, "mimetype_inner": null, "name": "eSPADE", "package_id": "e740ad88-dde7-4c3d-a9ae-2e3839ef20ca", "position": 1, "resource_type": null, "size": null, "state": "active", "tracking_summary": {"total": 909, "recent": 1}, "url": "http://espade.environment.nsw.gov.au", "url_type": null}], "tags": [{"display_name": "Land Degradation", "id": "3fbd33a0-903c-4da5-9e83-6cd803fa9452", "name": "Land Degradation", "state": "active", "vocabulary_id": null}, {"display_name": "Land Management", "id": "7dcd91f6-d8ec-4845-9e95-dd7d0cd99553", "name": "Land Management", "state": "active", "vocabulary_id": null}, {"display_name": "Salinity", "id": "3887ef53-2cd3-4676-9e6c-370e8f738dbe", "name": "Salinity", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "likes": 1, "tracking_summary": {"total": 97, "recent": 7}}}
