Data Quality

Lineage Habitat boundaries were interpreted from underwater features discernable on ortho-rectified aerial photographs. Year ranges of data capture for the following regionsSELECT 1 FROM DUAL; Adelaide Dolphin Sanctuary 2001-2006, Upper Gulf St Vincent and Upper Spencer Gulf 2005-2007. Adelaide Mt Lofty Ranges(AMLR) 2007-2008 and South East 2009-2010. Field observations and underwater video footage was used to capture the Upper Spencer Gulf and Upper Gulf St Vincent data. The AMLR data was captured from field observations, underwater video footage, acoustic mapping and sidescan sonar. The data sets were combined as part of a DEWNR statewide project. Additional data was captured on Kangaroo Island during 2013 which included field observations and Underwater video footage. This data was added by regional staff using an adapted data schema that now includes species specific information.
Completeness This dataset is considered complete.
Positional Accuracy Accuracy ranges from +/- 10m to +/- 20m.
