Title: Location and attributes of geophysical surveys acquired by State and Federal government agencies for various Initiatives to assist in better understanding South Australian geology.
Originator:
Custodian: Geological Survey of South Australia
Jurisdiction: South Australia
Description
Abstract:
This layer contains the digitally available geophysical surveys acquired by State and Federal government agencies for various Initiatives to assist in better understanding South Australian geology. Location and attribute data should help to decided if there is a survey over your area of interest and what technique was used in its acquisition.

Data Quality
Lineage:
The State and Federal government have funded several Initiatives over the last 60 years to reduce the risk to explorers in South Australia. Surveys contained in this data layer include work done under the PACE, TEiSA, SAEI and BHEI initiatives.
Positional Accuracy:
Accuracy is heavily dependent on the age of the data. Prior to the 1980’s survey lines were located by pilots referring to aerial photography and surface features while flying. During the 1980’s beacons were used to create a network of transmitters to triangulate position. During the 1990’s the Global Positioning System (GPS) came into use.
Attribute Accuracy:
90%
Logical Consistency:
Some polygons overlap but this is deliberate. New surveys are flown to allow overlap to aid leveling older datasets to new datasets. At least 800metres to 1000metres is preferred.
Completeness:
This shapefile represents an active dataset. It is accurate at the time of publication. It will be necessary to review annually to incorporate any new datasets. Attributes in the data layer are about 90 percent accurate at October 2009. The annual review process should improve this accuracy within a few iterations.
