The NSGM scheme is an extension of the Dove et al. (2016) approach, which characterises the seafloor in two sequential parts: Part 1 maps the seafloor Morphology (shape) using bathymetry data, and Part 2 uses additional data to interpret seafloor Geomorphology for those mapped morphological shapes. Part 1 of the NSGM scheme was applied to the project dataset, and consists of three hierarchical levels: Province, Surface and Feature. This dataset contains Surface shapefiles that comprise three categories: Plane (<2 degrees), Slope (2-10 degrees) and Escarpment (>10 degrees).This dataset is published with the permission of the CEO, Geoscience Australia {"type": "Polygon", "coordinates": [[[130.25, -12.725], [131.2, -12.725], [131.2, -12.125], [130.25, -12.125], [130.25, -12.725]]]} 130.25 131.2 -12.725 -12.125 Published_External seabed geomorphology Download the data (shp) [1 MB] documentDigital Download the data (shp) [1 MB] ZIP Link to collection record documentDigital Link to collection record HTML
