The classifications were validated with towed video ground truth where it was available. This dataset describes two AOIs which are explicitly part of the Ningaloo Outlook Deep Reefs project. Substratum classifications were applied using multibeam backscatter angular response curves along with rugosity as input to a maximum likelihood classifier. See original metadata record(s) and associated attached documents for accuracy estimates, alternate classification techniques, and additional surveyed areas. https://doi.org/10.25919/kssa-5b46 https://doi.org/10.25919/kttc-x397 https://doi.org/10.25919/8m65-7k26 {"type": "Polygon", "coordinates": [[[113.4948, -23.1576], [113.7808, -23.1576], [113.7808, -22.0689], [113.4948, -22.0689], [113.4948, -23.1576]]]} 113.4948 113.7808 -23.1576 -22.0689 Benthic habitat Substratum classification Temperate Reef SHAPE-ZIP documentDigital DATA ACCESS - This OGC WFS service returns the data (Ningaloo deep reef habitats) in Shapefile format WFS seamap:SeamapAus_WA_Ningaloo_deepreef_substrata_2019 documentDigital MAP - Ningaloo deep reef substrata WMS View and download this data through the interactive Seamap Australia data portal. documentDigital HTML ORCID ID documentDigital HTML ORCID ID documentDigital HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
