Background

...

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

Data Distribution Policies

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. 

Any moratorium dates must be provided as a “hard date” and will be adhered to post-submission systematically. (2year max, available only to certain parties – to be discussed further).The GA contributing 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 GA contributing hub for access to the supplied data. 

   1. As the GA contributing 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 contributing hub will be provided for release with appropriate attribution under the creative commons licence  (CCby 4.0) and ISO 19115-3 compliant metadata schema.

   1. Any data that GA is distributing on behalf of others must have a signed contributing data partner form provided with the data.

4. Data that arrives with a moratorium date will be automatically released at the end of moratorium.

   1. Data will only be accepted with a maximum 2 year moratorium, and permission to release a basic metadata record and associated polygon of the area covered by the data.
