Australian Coastal Sediment Compartments WFS

Brief description

The Australian Coastal Sediment Compartments Web Service provide a hierarchical spatial classification relevant to the assessment of sediment movement in the Australian coastal zone, and represent a tool to assist coastal planning and management. Additional spatial data layers produced during the development of the compartments are provided for reference.

Statement: The method used to create the polygon extents for the Realms, Regions and Divisions is not recorded but a review of the products suggests that they have not been derived from a digital elevation model or from buffering the coastline. It is believed the extents were digitised on-screen by hand with no further review of the extents, e.g. not clipped back to within Australia's Exclusive Economic Zone (EEZ). In developing the Primary and Secondary Compartment (polygon) data sets, the input data sets and basic process are presented below. Input data sets - The Australian Bathymetry and Topography Grid 2009 (used to define onshore and offshore bathymetric/elevation limits) - Primary and Secondary boundary points defining compartment limits on (or near) the coastline - Break lines connecting the landward to seaward extent via the Primary and Secondary compartment boundary points o Manually digitised on-screen through visual interpretation of the Australian Bathymetry and Topography Grid and SPOT/Landsat optical imagery to define onshore topographic barriers to sediment movement (e.g. ridges. - Australia's Exclusive Economic Zone (EEZ)
