Victorian Bathymetry Layer now discoverable in the AODN Portal


AODN staff have been working with Alex Rattray and Daniel Ierodiaconou from Deakin University‚Äôs School of Life and Environmental Sciences, over the last few months, with the initial work focusing on a Bathymetry data collection covering Port Phillip Bay, Victoria.  This was then superseded by a collection which represented the whole Victorian coastline, which can now be viewed on the AODN Portal here. This final product provides a gap free Digital Elevation Model (DEM) for the Victorian Coastal region, it was created from multiple products provided for the project, see the metadata record for further information.

The original data provided for this project was collected by:

  • Department of Environment, Land, Water and Planning (DELWP), Victorian Government
  • Port of melbourne
  • Deakin University
  • Royal Australian Navy
  • Geoscience Australia

 

The Victorian Coastal Digital Elevation Model (VCDEM) data product required development work at the AODN to take place, due to the unique properties of the dataset. Specifically, AODN infrastructure was modified to be able to aggregate very large (65GB) netCDF files containing a spatial subset, but without the presence of temporal subsetting information.  It is now fully functioning in the AODN Portal (link above), also check out other data collections in the Victorian Marine Data Portal which is a great example of the use of AODN Open Source Infrastructure being utilised.
