= UK e-Science All-hands Meeting, Nottingham, 10-12 Sep. 2007 = * Peter's notes. * [http://www.allhands.org.uk/programme/index.cfm Programme and links to proceedings] * [http://www.allhands.org.uk/2007/proceedings/programme.htm Index to proceedings] == Future of e-Science - Prof. Ken Brodie, UK e-Science Envoy == * Summary of activity last year, e.g. National Grid Service, meetings, etc. * Recommended article: [http://www.cs.cmu.edu/~wing/publications/Wing06.pdf Computational thinking] by Jeanette Wing. * Swedish meeting: [http://www.vr.se/mainmenu/pressandnews/newsarchive/news/howcansciencebeimprovedbyescience.5.315d803911100fdce718000382.html How can science be improved by e-Science?] * Little on the future of e-Science. == 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 == * [http://www.nesc.ac.uk/talks/ahm2007/792.ppt Presentation] and [http://www.allhands.org.uk/2007/proceedings/papers/792.pdf 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. * [http://lovejoy.nerc-essc.ac.uk:8080/Godiva2/ Godiva2], [http://lovejoy.nerc-essc.ac.uk:8080/ncWMS/godiva2.html DEWS NetCDF version], [http://lovejoy.nerc-essc.ac.uk:8080/ncWMS/mersea.html 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. * http://www.eviz.org/ * 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 * http://www.niees.ac.uk/wkml * 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.
