Description: This layer is reclassified from the following datasets: Acid Sulphate Soils Risk Mapping (Department of Environment and Climate Change NSW), Quaternary Geology - Comprehensive Coastal Assessment Toolkit (DoP NSW), Land Resources of NT 1:25,000 (Natural Resources, Environment, The Arts and Sport NT), Foreshore, dune and shoreline stability classifications between Guilderton and Dongara (Department of Environment and Conservation (DEC) WA). The source data was captured at 1:250,000, 1:100,000 and 1:50,000 scale. In the geodatabase structure there was no attempt to create a single scale product by re-sampling or interpolating between scales. This was to ensure that users of the National Coastal Geomorphology data did not utilise data at inappropriate scales, while retaining the maximum amount of information where it existed.

Description: Mapped coastal geomorphology is a fundamental dataset required by all levels of government to successfully address the potential impacts of climate change, including sea level rise and increased intensity of storm surge events, in the coastal zone. This is of particular importance in Australia because the majority of the population resides within this portion of the continent. A digital coastal geomorphology map, combined with a high resolution digital elevation model, will allow for detailed sea-level rise and recession modelling and assist in the identification of potentially susceptible landform units (natural or man-made). By mapping the spatial extent of vulnerable landform units, it is possible to identify the landward extent of potential short-term erosion and long-term recession. Geoscience Australia has developed a national coastal geomorphology classification scheme. This scheme was developed through extensive review of coastal literature, pre-existing coastal classification schemes and datasets. The scheme adopts a hierarchical form (morphology) and fabric (composition) based classification. The rationale behind this lies in the usefulness of form and fabric classification in the identification of potentially vulnerable natural landform features as well as anthropogenically altered surfaces, and the ease at which these structures translate into a GIS database. The classification scheme identifies the main process (i.e. alluvial, anthropogenic, estuarine, coastal or marine) acting on a feature as well as its form and fabric. Five classes are used to describe the substrate (hard or soft), depositional system, depositional environment, sediment texture or lithology and habitat of each polygon feature. Geoscience Australia has completed the first phase of an areal map of Australia’s coastal geomorphological units. Utilising pre-existing GIS datasets procured from local, state and federal government agencies, this national scale map conforms to a coastal geomorphology classification scheme developed at Geoscience Australia. Phase one consists of a geodatabase containing a series of state wide feature datasets that have been reclassified into the national coastal geomorphology classification scheme.
