6. Virtual Geophysics Laboratory | Joshua Vote 6 | Introducing The Virtual Geophysics Laboratory

7. Data discovery Virtual Geophysics Laboratory | Joshua Vote 7 | Layers discovered via remote registries Layers consist of numerous remote data services

8. Data discovery Virtual Geophysics Laboratory | Joshua Vote 8 | Some data services support subsetting Some data services support reformatting e.g. CSV, NetCDF, GeoTIFF

9. Data discovery Virtual Geophysics Laboratory | Joshua Vote 9 | Some data is only registered with flat files

10. What just happened? Virtual Geophysics Laboratory | Joshua Vote 10 |

11. Data processing Virtual Geophysics Laboratory | Joshua Vote 11 | A variety of different scientific codes are already available in the form of “Toolboxes” Flexibility in what computing resources to utilise

12. Data processing Virtual Geophysics Laboratory | Joshua Vote 12 | Further input files can be uploaded. Input files are passed directly into the cloud

13. Data processing Virtual Geophysics Laboratory | Joshua Vote 13 | The steps so far have been building an environment to run a processing script...or build from existing templates Either write your own...

14. What just happened? Virtual Geophysics Laboratory | Joshua Vote 14 | Processing script/ small input files uploaded Start processing Download big data sets Perform data processing Download Job Script/user input files Upload processing results

15. Managing results - provenance Presentation title | Presenter name 15 | All of a job’s outputs are also accessible Each job has a lifecycle that can be managed Virtual Geophysics Laboratory | Joshua Vote 15 | A job’s console log can be inspected

16. Managing results - provenance Virtual Geophysics Laboratory | Joshua Vote 16 | Successful jobs can have their entire process captured in a ISO 19115 ‘provenance record’ Each provenance record tracks all inputs, outputs, processing scripts and other metadata.... Spatial bounds... Input/output data...

17. What just happened? Virtual Geophysics Laboratory | Joshua Vote 17 | What’s the processing status? What are the job input/outputs? Publish the job’s process and results Cloud storage will persist the final artefacts

18. Still under construction Virtual Geophysics Laboratory | Joshua Vote 18 | Courtesy - www.textfiles.com

19. What’s left? A Common Processing Services Platform Analytical Spatial Information Services Stack (ASISSt) Virtual Laboratory client toolkit VGL Improvements More data and models HPC Integration Your code here! Virtual Geophysics Laboratory | Joshua Vote 19 | Analytical ASISSt +
