Victorian Coastal Digital Elevation Model 2021 (VCDEM) - 10m

dataset: VicCoastDEM2021_10m
The Victorian Coastal Digital Elevation Model 2021 (VCDEM) incorporates several new datasets to previous versions of the dataset created in 2017 and 2010, integrating new bathymetric datasets to the VCDEM product. The VCDEM dataset is foundational to the Victorian Coastal Mapping Program (VCMP) and updates to the VCDEM will improve the understanding of dynamic coastal processes and their associated risks advanced by the VCMP. The VCDEM2021 produced by Veris is comprised of two major outputs: 1. HIGH RESOLUTION VCDEM2021 Contains gridded data sources with a gridded spatial resolution (pixel size) equal or superior to 10m in addition to vertical uncertainty meeting IHO Order 1b specifications (ie better than 0.5m). The high resolution VCDEM2021 will necessarily contain gaps where data does not meet these conditions. 2. SEAMLESS VCDEM2021 Contains gridded data sources with a gridded spatial resolution (pixel size) equal or superior to 10m in addition to vertical uncertainty meeting IHO Order 1b specifications (ie better than 0.5m). Low resolution bathymetric data is used in areas with no high resolution bathymetric coverage and algorithms are used to merge bathymetric to a seamless product.

Statement
The bathymetric data was collected from Deakin Uni, DELWP, Frontier SI, GA, Gippsland Ports, Royal Australian Navy as well as Port of Melbourne. The GIS data was generated by integrating the bathymetric data within ArcGIS software 
Description
Over 150 datasets have been merged to create the Victorian Coastal DEM 2021. A full list can be found by contacting the Victorian Coastal Monitoring Program and supported metadata spreadsheet.
