SA Geodata: vital asset

An essential database for the resources sector.

The provision of high-quality information to industry allows better understanding of the resource potential within South Australia and more confident decisions about how and where to invest in exploration within the state. The government uses the same information to support decision-making, including regulation, promotion of the state to attract investment, and how best to invest to improve our understanding and management of the state's resources.

SA Geodata is South Australia's chief repository for most forms of geoscientific data, and is the source of the vast majority of the data provided via SARIG. By analogy, it’s the data warehouse that sits behind the shopfront.

Jointly owned by the Department of the Premier and Cabinet (custodian of mineral resources data) and Department of Environment, Water and Natural Resources (custodian of groundwater data), the database integrates all sources of state-owned geoscientific data into a one-stop resource.

Fast facts

  • Contains data for about 1.6 million locations around South Australia, covering approximately 160 years of geological exploration
  • Includes almost 300,000 drillholes, 1.85 million rock samples, over 90,000 field observations and over 8,000 mineral deposits or occurrences
  • Includes about 20 million geochemical analysis results, 112,000 drillhole geological logs, 60,000 surface structural measurements, along with petrological observations, rock property and biostratigraphic data
  • Provides a catalogue of drillhole and rock sample holdings at the South Australia Drill Core Reference Library
  • Aids identification, naming and describing of the state's stratigraphic units
  • Aids the management and tracking of company exploration reporting

Into the future

A new module to manage and deliver geochronological and isotope geochemistry data will be released in 2018. Other developments will include better management and delivery of petrographic data, modernisation to cater for the move to a new geographic datum for Australia, and web services options for data delivery.

The rapid appearance of new technologies for data collection and new analytical techniques is leading to exponential increases in the amounts and types of data to be stored and managed (Fig. 1). Planning for the future, while maintaining its outstanding existing capabilities, is a primary focus for the SA Geodata team.
