Seafloor classification of the bathymetry dataset from the Queen Charlotte Sound / Tōtaranui and Tory Channel / Kura Te Au Hydrographic Survey LINZ Project HYD-2016/17-01 (HS51).

Classification of the multibeam data based on the backscatter intensity as a proxy for substrate type. Classification was done using the ArcMap Image Classification tool using four classes. Training areas where picked to identify areas from high to low backscatter.

These data are in raster geotiff format and include ESRI layer files and QGIS GML files for symbology.
