Topography - Coastline

Dataset Number970
Dataset TitleTopography - Coastline
CustodianData Authority: Department for Environment and Water
Data Provider: Department for Environment and Water

Description

DescriptionData layer includes an interpretation of the mean high water mark for the coastal zone of South Australia. This layer is a historic representation of the Mean High Water mark. It has been captured from now historic Ortho rectified imagery using heads up digitising techniques.
UsageStandard layer of topographic dataset. This coastline representation should only be used for a generalized mapping where accurate representation is not required.

Data Quality

LineageThe coastline was re-interpreted and re-captured in 2005 from ortho-rectified aerial imagery of varying specifications. Reference was also made to advice from DEH Coast and Marine sources and in limited instances, field inspection.
CompletenessDataset is complete for South Australia
Positional AccuracyIn general, 90% of well defined features are within +/- 25metres of their true position. Ill defined features are subject to interpretation error and their accuracy is generally beyond this level. Horizontal accuracy is also recorded at the feature level.
