The final gridded surface was generated by merging all grids using a bulk-shit approach, i.e., average discrepancy in depth (m) in areas of overlap, over consecutive days, using the earliest mosaic as reference.

and assessment of change at key focus areas'.

Data is supplied as a single Web Map Service of hillshaded bathymetry for the mapped region. Data is available for download as (1) bathymetry, and (2) hillshade tiff files.
