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.
