2. State government geophysical data are now available from GADDS

Airborne geophysical datasets acquired by the Queensland and Victorian State governments are now available for free download from GADDS (Geophysical Archive Data Delivery System).

With the addition of airborne geophysical survey datasets from the States, GADDS is now delivering data through the geoscience portal http://www.ga.gov.au/gadds

The main features of GADDS remain unchanged:

1. Data is requested using a standard web-browser.
2. Only the data required by the client is delivered to the client.
3. Choose the data format (ASCII columns or Intrepid Database) for data delivery, and the required datum and projection.
4. Both vector (line and point) and raster (grid) datasets are delivered to the user.
