Full description
The Seamap Australia National Benthic Habitat Layer (NBHL) is a compilation of benthic habitat datasets obtained from various sectors including research, government, industry and community sources, across Australia. These disparate datasets have been integrated into a single national-scale benthic habitat database, and classified uniformly under a national classification scheme implemented as a controlled vocabulary (https://vocabs.ardc.edu.au/viewById/129). Creation of this classification scheme complements work undertaken by the National Environmental Science Program (NESP) Marine Biodiversity Hub (Theme D). For acceptance into the Seamap Australia NBHL, source habitat datasets must meet a set of Acceptance Criteria (documented in https://seamapaustralia.org/wp-content/uploads/2023/01/SeamapAustraliaDataAcceptanceGuidelines.pdf). Broadly speaking, for inclusion in the Seamap Australia NBHL, datasets must: (1) be well-described by metadata or associated documentation; (2) employ a single, consistent classification scheme which avoids non-deterministic or ambiguous terms; (3) be quality-controlled by the provider prior to contribution; (4) beacquired using an established and community-endorsed form of data collection (eg satellite, aerial or acoustic remote sensing); and (5) have documented evidence of ground-truthing validation at the time of data collection (e.g. drop camera, towed video, benthic grabs). The Seamap Australia NBHL can be viewed, analysed and downloaded from the Seamap Australia data portal (https://seamapaustralia.org/map) – a national repository of seafloor habitat data and a decision support tool for marine managers. All habitat datasets in the Seamap Australia data portal, including the NBHL and all local- to regional-scale contributing datasets, are available for download. The Seamap Australia NBHL is a data collection of national importance and highlights the diversity of benthic habitats across Australia’s marine estate. This is the first Australian habitat dataset that seamlessly consolidates data from each of Australia’s state and territory providers. This dataset should be considered a “live” asset and will continue to develop as more suitable validated habitat data becomes available for inclusion, and improvements in data collection and analysis techniques enhance its resolution and currency. The most current (2026) version of the data is available from the following endpoints: WMS: https://geoserver.imas.utas.edu.au/geoserver/seamap/wms WFS: https://geoserver.imas.utas.edu.au/geoserver/seamap/wfs Layer name: SeamapAus_National_Benthic_Habitat_Layer A download link for the full dataset is supplied in the 'Download and Links' section of this record, along with download links to older versions of the dataset. Note that data is now only available in Geodatabase (.gdb) format as it exceeds Shapefile size limits.Lineage
Statement: A full report outlining the methods utilised to create the Seamap Australia National Benthic Habitat Layer is available online at https://seamapaustralia.org/wp-content/uploads/2018/12/Seamap-Australia-Report_18_12_11.pdf In brief: source datasets were assessed for suitability by considering collection and analysis methodology to derive the habitat maps. Data Acceptance Guidelines (see https://seamapaustralia.org/wp-content/uploads/2023/01/SeamapAustraliaDataAcceptanceGuidelines.pdf) stipulate the minimum quality requirements for data to be considered for inclusion in the NBHL. All source datasets meeting minimum quality requirements were classified according to the Seamap Australia Classification Scheme (see https://seamapaustralia.org/resources/classification/ for a visual guide). The original classification is retained and can be identified on a per-polygon basis within the full dataset. Source datasets were prioritised according to currency, collection methodology, spatial and taxonomic resolution, and combined into a single dataset using GIS tools ERASE, MERGE and UNION (ArcGIS). Note that the Seamap Australia Classification Scheme has separate biotic and substratum components, which may be contributed from different source datasets. The dataset was then dissolved into multipolygons and basic spatial cleaning was performed (INTERSECT and DELETE IDENTICAL to remove overlapping polygons, INTEGRATE 0.1m, REPAIR GEOMETRY). See https://seamapaustralia.org/wp-content/uploads/2023/01/Updating_Seamap_NBHL_v1.0.pdf for full methodology outlining the update process.Notes
