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.

Chat with Keith Haynes, Reading e-Science Centre

  • He demo'd Godiva2, nice Ajax-driven interface with clear date display/selection, nice 'fit data to window' and 'auto-colour-scale' buttons, automatic display of same region/closest time when switching datasets. We should learn from it.
  •  Godiva2,  DEWS NetCDF version,  MERSEA version.
  • Keith would like to have an NCOF version, also biological data from PML - I said this should be done through Tim's WCO, could go in other WMS servers in addition to the PML one.
  • I asked about Godiva2 for NDG visualisation, he said this should be possible if served as CF-netCDF by WMS.
  • I demo'd the PML WMS client, he thought it was quite fast and wondered if the images are pre-generated or on the fly, e.g. can we change colour scale?

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

  • Modelling cell development, web services, databases, FuGE-OM?

Visualisation Session

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

  • Quite interesting, uses Java tool eViz and extended skML to describe visualisation components and controls, generates user interface with minimal coding.
  • Could be used in NDG?

Driving Google Earth from Fortran, Gen-Tao Chiang

  • Simple KML library, e.g. kmlBeginFile(...), kmlCreatePoints, ...Line, ...Contour, ...Cells (for 2D grid), can plot 2D grid by colour, contour or height, e.g. Greenland ice thickness
  • Could wrap it into C, IDL, etc. Jon Blower suggested an IDL kml_write function for any generic data type as if a file format like GIF.

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

  • e.g. RAVE, GVK, StreamAR.

Data Handling and Service Deployment Session

Deploying visualization applications as remote services, Mark Riding

  • More on eViz, nice example of how to register a new visualisation tool.

Booth demonstation sessions

BAS Research real-time display in GE, Peter xxx and Nathan

  • I added in near-real time EO data.
  • Nathan is coordinating GEO-Ocean user group, including me and Tim.

OceanDIVA - tools for presenting datasets in GE

  • Nice plots of model skill vs in situ

gXXX - cluster submission & retrieval of data files

  • Transfers and deletes model output files from cluster to local computer.
