The three broad-scale polygon data layers - Coastal Realms, Regions and Divisions - capture high-level environmental attributes and information, and were developed as an informal hierarchy. These three data sets are supplied as they provide context and a logical sequence for the development of the compartments. With regards to spatial scale, a hierarchical listing for data sets is given below: - Coastal Realms (1:5 000 000) - Coastal Regions (1:1 000 000) - Coastal Divisions (1:250 000) - Primary Compartments and Points (1:250 000 - 1:100 000) - Secondary Compartments and Points (1:100 000 - 1:25 000) The Primary and Secondary Coastal Sediment Compartment (and Point) data sets represent a regional (1:250 000 - 1:100 000) and sub-regional (1:100 000 - 1:25 000) scale compartmentalisation of the Australian coastal zone into spatial units within (and between) which sediment movement processes are considered to be significant at scales relevant to coastal management. The Primary and Secondary Point data sets were generated and attributed using expert panel knowledge of coastal geomorphology and processes, and represent compartment boundaries along the coast at the respective scales. Environmental attributes used to determine the location of compartment (point) boundaries are given in priority order below. 1 - Gross lithological/geological changes (e.g. transition from sedimentary to igneous rocks). 2 - Geomorphic (topographic) features characterising a compartment boundary (often bedrock-controlled) (e.g. peninsulas, headlands, cliffs). 3 - Dominant landform types (e.g. large cuspate foreland, tombolos and extensive sandy beaches versus headland-bound pocket beaches). 4 - Changes in the orientation (aspect) of the shoreline. Once generated, the compartment boundary point data were used in conjunction with a number of other input data sets to generate the Primary and Secondary Compartments. Use Limitations: The Realm, Region and Division data sets are interim products used to establish a context for the development of the Primary and Secondary points and compartments. There is no formal topological relationship between the Realm, Region and Division data sets. An informal hierarchical (not topological) relationship does exist between the Primary compartments and the Divisions, as seen in the Primary compartment attribute field ID_Primary. The Primary and Secondary compartments do share a formal topological relationship, and also a formal hierarchical relationships, as shown in the Secondary compartment attribute fieldID_Secondary. Primary compartments are intended to be representative at a spatial scale of 1:250 000 - 1:100 000 while secondary compartments are intended to be representative at scales from 1:100 000 - 1:25 000. IT IS IMPORTANT TO NOTE THAT THE COMPARTMENT POLYGON DATA IS NOT ATTRIBUTED WITH ENVIRONMENTAL DATA - ONLY THE PRIMARY AND SECONDARY POINT DATA SETS CONTAIN SUCH ATTRIBUTE DATA. {"type": "Polygon", "coordinates": [[[111.0, -45.0], [155.0, -45.0], [155.0, -9.0], [111.0, -9.0], [111.0, -45.0]]]} 111.0 155.0 -45.0 -9.0 Data Package Earth Sciences Geosciences National Published_External boundaries environmental Download the map (Primary Coastal Sediment Compartments) documentDigital Download the map (Primary Coastal Sediment Compartments) JPEG Download the map (Secondary Coastal Sediment Compartments) documentDigital Download the map (Secondary Coastal Sediment Compartments) JPEG Related product: The Australian Coastal Sediment Compartments Project: Methodology and Product Development documentDigital Related product: The Australian Coastal Sediment Compartments Project: Methodology and Product Development HTML Download the data (ESRI shape file) documentDigital Download the data (ESRI shape file) ZIP Download the data (ESRI file geodatabase) documentDigital Download the data (ESRI file geodatabase) ZIP Download the data (Google kmz) documentDigital Download the data (Google kmz) ZIP Related product: Australian Coastal Sediment Compartments ESRI Mapserver documentDigital Related product: Australian Coastal Sediment Compartments ESRI Mapserver HTML Related product: Australian Coastal Sediment Compartments WMS documentDigital Related product: Australian Coastal Sediment Compartments WMS HTML Related product: Australian Coastal Sediment Compartments WFS documentDigital Related product: Australian Coastal Sediment Compartments WFS HTML Unnamed resource documentDigital HTML
