UK e-Science All-hands Meeting, Nottingham, 10-12 Sep. 2007

Future of e-Science - Prof. Ken Brodie, UK e-Science Envoy

GEO Grid: Systems federating Geospatial Data and Services, Mr Satoshi Sekiguchi, Japan

  • Using ASTER data on Terra - archive 2000-date, 1.4 million images, 140 TB. VNIR 3 bands, SWIR several, TIR several. Together with 15m DEM.
  • e.g. Landslide volume estimation, volcano prediction, etc.
  • Uses OGC interfaces, simple workflow engines and user services e.g. thumbnail pages.

Sharing and visualizing environmental data using Virtual Globes, Jon Blower, Reading e-Science Centre

  •  Presentation and  paper.
  • Virtual Globes - there are 30 of these (incl. GE, MS Virtual Earth, FreeEarth, !ArcGIS Explorer, NASAS WorldWind), many free!
  • Movie of Hurricane Katrina, cooling SST as intensifies, also CASIX, etc.
  • BODC use GE as Discovery/Browse? tool.
  • BAS use GE for King Penguin tracks overlaid on NEODAAS chl-a imagery.
  • Can extend the VG if open source, e.g. ArcGIS Explorer, NASA WorldWind using .NET API.
  • OceanDIVA: Ocean data assimilation for ESSC using GE.
  • Vertical structure of ocean, tried 4 layers above ground(!) using GE, need extension.
  • GML for more complex datasets than KML can handle, a la NDG, though not many tools available yet. Should be used to encode data for true interoperability, needs concerted effort on feature types.
  • WebGIS are alternatives to VG, e.g. GoogleMaps.
  • EU INSPIRE mandate - all public bodies must provide discovery/view/download services. 80% of all business/gov info has reference to location.

Interoperability Session

JSDL Application Repository and Artefact Sharing Portal for Heterogeneous Grids and the NGS, David Meredith

  • JSDL is an XML language for describing requirements of computational nodes for submission to a grid.
  • Sits above middleware-specific job desc. languages, copes with grid heterogeneity.
  • Online demo of NGS Job Portal.

Two other talks in this session, not very relevant.

The Grand Challenge of Population Ageing: e-Science to the Rescue, Prof Thomas Kirkwood: University of Newcastle

Visualisation Session =

A user interface framework for Grid-based computational steering and visualization. Jason Wood

Driving Google Earth from Fortran, Gen-Tao Chiang

A Service Agreement Framework for Grid based Distributed Rendering, John T OBrien
