Dataset Number 893 Dataset Title State Marine Park Network Points Custodian Data Authority: Department for Environment and Water Data Provider: Department for Environment and Water

Description Description This dataset identifies the longitude and latitude of the South Australian Marine Park outer boundaries at different locations within the state. For example where the boundary meets the state waters, coastline (median high water), DCDB and where the boundary changes direction within state waters. Following a public consultation process, the marine park boundaries were re-proclaimed on the 23rd July, 2009 to include some changes. This dataset was updated in August 2011 due to an update in the ports spatial layer provided by PIRSA. This dataset relates to the coordinates of the outer boundaries only. Internal marine park draft zoning coordinates will be released late 2012. Usage Defines coordinates of the outer boundaries of the South Australian Marine Parks Network.

Data Quality Lineage Points were digitised on screen at a scale >1:1000 in GDA 94 geographic. These points were digitsed at locations where the marine park boundaries meets the state waters boundary, median high water, Cadastral parcels (DCDB) and were the boundary changes direction within state waters. Completeness Dataset is complete. Positional Accuracy The positional accuracy of the South Australian Marine Parks Network (Boundaries) coordinates is related to the positional accuracy of the following data sources South Australian (SA) coastline (median high water), Australian Maritime boundaries, Cadastral (DCDB) and NPWSA boundaries. The positional accuracy for data captured from the DCDB and NPWSA layers is dependent on the map scale from which the parcels were originally captured. The total of the data captured from the DCDB and NPWSA layer is 25%. Data captured from the SA coastline positional accuracy is quoted as +/- 25 metres which is 30% of the data. The positional accuracy of the data captured from the Australian Maritime boundaries is quoted as +/- 150 metres which is 16% of the data. Data captured within state waters has a positional accuracy of +/- 20 metres which is 27% of the data. The South Australian Marine Parks Network (Boundaries) coordinates will be further verified in 2009.
