Estuarine Habitats of South Australia

Dataset Number1581
Dataset TitleEstuarine Habitats of South Australia
CustodianData Authority: Department for Environment and Water
Data Provider: Department for Environment and Water

Description

DescriptionThese datasets contain habitat mapping and outer boundaries for estuaries of South Australia. These estuaries were identified in the draft 'Estuaries Policy and Action Plan.'
UsageUsed to identify the estuarine habitats within South Australia for use in natural resource management and conservaton planning. Description of attributes in related Inventory and Water Quality tables can be found in report: 'Working Towards a State-wide Inventory of Estuaries 2009 - Advancing the inventory of estuaries in five Natural Resource Management Regions of South Australia', DEH and Adelaide Mounty Lofty Ranges NRM Board (in prep).

Data Quality

LineageUsing estuaries that have been identified as part of the draft 'Estuaries Policy and Action Plan for South Australia' habitat boundaries were delineated using existing benthic habitat mapping and saltmarsh and mangrove habitat mapping and additional line work digitized from aerial photography. Digitization was undertaken in the DEH's SDE edit environment to map vegetation and landform boundaries that were located by a combination of air photo interpretation, heads-up orthophoto digitisation, field capture and integrated line work from the above mentioned existing spatial data sets. Imagery was sourced from the most up to date available in the DEH image library at the time of completion and as such imagery was undertaken using images at a variety of scales (refer to positional accuracy).
CompletenessThis dataset is complete for all of the estuaries identified in the draft 'Estuaries Policy and Action Plan' 2007.
Positional AccuracyThe majority of mapping is based on 1:2,500, 1:10,000, 1:15,000, 1:40,000 & 1:80,000 digital orthophotograhy. Due to the varying imagery used in capture the positional accuracy may vary but may be accepted to be +/- 15m for all purposes.
