NIWA's bathymetry model of New Zealand at a 250m resolution. The 2016 model is
a compilation of data digitised from published coastal charts, digital soundings
archive, navy collector sheets and digital multibeam data sourced from surveys
by NIWA, LINZ, as well as international surveys by vessels from United States of
America, France, Germany, Australia, and Japan. All data used is held at NIWA.Image service can be used for analysis in ArcGIS Desktop or ArcGIS Online - no need to download the data, just stream using this service and classify, symbolise, mask, extract or apply map algebra - just like you would with local raster files. https://enterprise.arcgis.com/en/server/latest/publish-services/windows/key-concepts-for-image-services.htmMap information and metadata
