There are now two more dataset collections published in the AODN Portal as part of the work forming the Australian Research Data Commons (ARDC) funded Marine Research Data Cloud (RDC) program, read about other work here. These dataset collections were made available in collaboration with Geoscience Australia (GA).
The Australian Seabed Sediments Collection contains data describing the physical properties of marine sediments dating from 1905 to 2017. It is a collation of samples acquired by marine surveys from various organisations with varying techniques, accuracy and preservation. It is available to download in CSV format.
The MH370 Phase 1 150m Bathymetry datasets (GA-4421, GA-4422 & GA-4430) collection contains over 710,000 square kilometres of data from bathymetric surveys conducted from June 2014 to February 2017. GA provided expertise and support to the Australian Transport Safety Bureau (ATSB) to facilitate the surveys. This data is available as GeoTIFF.
To publish these datasets on the AODN Portal AODN staff assisted GA scientists and developers to configure and update the required services which included but was not limited to:
- Implementing a Web Map Service (WMS),
- Configuring relevant filters to enable sub-setting in the AODN Portal,
- Implementing a data download service using a combination of Web Feature Service (WFS and a Web Coverage Service (WCS).
AODN staff also completed the following tasks:
- Harvesting an Iso 19115-1 metadata record from the GA metadata catalogue and inserting relevant content using AODN published controlled vocabularies to facilitate the faceted search function,
- Finalising configuration and testing in a temporary stack.
Each collection required different configuration and set up to successfully integrate with the AODN Portal.
The Seabed Sediment collection currently sits in a database where data is maintained and extractable via a web interface, however GA intends to upgrade the database and access points so the interim solution implemented was to construct static web services to satisfy RDC requirements. This resulted in a new dataset being created in Geoserver, where WMS and WFS were configured for AODN Portal ingestion.
For the Bathymetry collection GA utilised infrastructure on the Amazon Web Services (AWS) platform to configure existing web services and establish a data ingestion process to allow integration with the AODN Portal. The existing WMS layer was configured and updated for this collection and changes were made to the AODN Portal code to handle GA’s “clip, zip and ship” download service as a recognised service, enabling the appropriate request to be sent to the GA download service allowing AODN Portal users to download the data via GA in GeoTIFF format.
The AODN thanks the staff at Geoscience Australia for assistance in making these collections available.
