GA Satellite Imagery Project

NOTE! DRAFT ONLY - UNDER INTERNAL REVIEW
Geoscience Australia (GA) is the national custodian of information vital to the Australian industry, government and research communities. AuScope Grid (AG) has a number of projects through which they are currently revealing GA data in an interoperable format:
- Geodesy WFS [AG]
- Geological Unit, Fault, Contact OneGeology Web Mapping Services (WMS) and WFS [AG]
- Geotransects (seismic data) [AG]
The Australian Spatial Research Data Commons (ASRDC) and AG projects will assist GA with SISS deployment for their LandSat satellite imagery data. The Satellite Imagery project aims to make this data accessible to the research community and reveal it through a coverage service.
The project encompasses:
- Interoperable access to GA Satellite data
- Visualisation of GA's Satellite data
- Coverage service support for GA's Satellite data (Coverage Setup)
The data will be hosted as an official GA mirror at the National Compute Infrastructure (NCI) facility at the Australian National University (ANU). All project services will also be deployed at NCI.
GA will provide an official mirror of their Satellite data at NCI. This mirror will be used as the basis for interoperable delivery of the Satellite data using a selection of open source services (the spatial information services stack - SISS) also deployed at NCI.
ASRDC recognise that a coverage service will need to be deployed in order to deliver this data effectively.
GA currently provides Satellite Imagery data from through a number of services, some of which are direct download services. Of particular convenience to the research community is access to limited cut-sets of the Satellite Imagery in an interoperable delivery format that is useful for subsequent manipulation.
GA require a solution that will make their Satellite Imagery data available for interoperable use to researchers.
ASRDC will work with GA to achieve the following objectives:
- Hosting of data (at NCI as an official mirror)
- Infrastructure to host SISS services (at NCI)
- Accessibility of hosted services
- Suitable resources for service deployment and support
The project covers the following GA Satellite data:
The uses cases covered can be found in the implementation pages: ...
The project will deliver the following:
- Satellite data officially mirrored at NCI
- SISS deployment at NCI to reveal the Satellite data interoperably
- Satellite data revealed through coverage services
Out of Scope Key Features
The Project will not
deliver the following:
- Coverage Processing Service - while this project will open up the opportunity for eventual integration with a coverage processing workflow, this is explicitly not included in the scope of the project. The knowledge imparted as part of the Geodesy and VEGL projects may be of assistance in future changes of this nature.
The following projects are related to this project:
The key stakeholders have been identified as:
| GA Satellite Data Admin
|| Key administrator and custodian of the data and the deployment
|| Assist with implementing services for data interoperability deployment
| AuScope Community
|| Benefiting end-user group
|| Maintains a national research data registry
High Level Plan
It is assumed that:
- GA will establish an official mirror of GA Satellite data at NCI
- Satellite data has appropriate licensing to be able to be distributed via the services stack
- NCI will provide appropriate infrastructure for hosting of necessary services stack
- NCI have and will provide support for future sustainability of services and subsequent updates
The project is constrained by:
