NeCTAR Virtual Geophysics Laboratory (VGL)

The VGL development overview can be found at VGLDevelopmentOverview

Overview

The Virtual Geophysics Laboratory ( VGL ) is a scientific workflow portal that provides Geophysicists with access to an integrated environment that exploits eResearch tools and Cloud computing technology. It is a collaboration between CSIRO, Geoscience Australia (GA), and the National Computational Infrastructure (NCI), and has been funded by the Federal Government’s Education Investment Funds through NeCTAR.

The VGL provides scientists with an easy agent to exploit multiple technologies provided by eResearch and Cloud in a user driven interface. It was developed in close collaboration with the geophysics user community and, with representatives from GA, ANU, Monash, and UQ, and has been deployed directly into their environment.

VGL workflow provides direct access to a large collection of datasets and models (supplied by Geoscience Australia) which include the National Airborne Geophysical Database (Gravity, Radiometric, AEM, Magnetics) and 3D model library. The workflow will have a spatial environment for users to select and sub-set datasets of interest ready for download or for processing. The workflow will include a section to "run your science" where the user will be able to setup a processing job to analyse selected datasets. The processing can then be submitted to the Cloud for execution and return results into a Result Registry. At completion of the simulation, users can retrieve results from the Result Registry for archiving, sharing and/or later use. This final step will assist in ensuring simulations are replicable as data is collected throughout the workflow describing the steps taken, datasets used, versions of code etc and registered in the registry.

VGL has been developed to reduce some of the technical barrier for geophysicians to exploit eResearch and Cloud technologies. It targets scientists that want to simply focus on doing the science and not have to learn all the "ins and outs" of HPC and cloud technologies. As the VGL runs various "workflows" these could be used extensively in an operational circumstance or educational environment. Finally, other developers could re-purpose VGL for other domains that process spatial data.

Project Details

The VGL is a Project funded under the NeCTAR Early Activities Program. Details of the Early Activities Program are documented in section 5.4 of the NeCTAR Project Plan.

The VGL builds off The "Virtual Exploration Geophysics Laboratory" ( VEGL) which was focused on an exploration use case and tied to a commercial/licensed computational code.

The VGL is a new effort to make this workflow available to a larger community and incorporate open licensed computational codes and data resources.The VGL will include the VEGL (remove the branding and only accessible to a limited audience due to licensing) and all the open sourced computational components (open to all)
