Background

Purpose

...

The GA Local hub will distribute data from a multi-organisation data collection. The GA Local Hub has prepared a series of distribution policies that help shape the outgoing data into consistent, useable and interoperable outgoing datasets.

Data Distribution Policies

The GA Local Hub will provide:

1. Public access to the L3 grid data as a 32bit floating point GeoTiff. Data will be available through the AusSeabed Marine Data Portal.

2. In specific cases, authenticated access may be provided to the L2 and L0 data stored within the AusSeabed GA Local Hub for access to the supplied data. 

   1. As the GA data hub matures, it is expected that the L2 and L0 data will also be made publicly available, through a managed interface to ensure the cost of egress and storage is well managed.

3. Data provided to the GA Hub will be provided for release with appropriate attribution under the creative commons licence  (CCby 4.0) and ISO 19115-3 compliant metadata schema.

4. Data that arrives with a moratorium date

1. Data must arrive with the associated minimum metadata as outlined in version 2.0 of the multibeam guidelines for it to be subsequently distributed. 

2. Submitters will be asked to attribute a creative commons distribution licence to their data, with allowance for a moratorium period to be implemented if required.
