  1. Harmonisation of Grid and Geospatial Services Standards in the Earth and Environmental Sciences Simon Cox1, Lesley Wyborn2, Andrew Woolf3, Robert Woodcock1, Rob Atkinson4, Joan Esterle1 1CSIRO Exploration and Mining2Geoscience Australia3e-Science Centre Rutherford Appleton Lab4Social Change Online 24 May 2005

  2. Overview • e-Science / NERC Datagrid • Oceans & Atmospheres data • Solid Earth and Environment community • HPC services for simulation & inversion • Standards-based loosely-coupled data services • SEE Grid Cox/2005 AGU Spring

  3. GridFeature ProfileSeriesFeature ProfileFeature BADC NERC DataGrid - data transfer • Focus on large datasets, simple structures • Time-series, profiles, gridded datasets • Series and collections • e.g. Climate Science Modelling Language (CSML) Cox/2005 AGU Spring

  4. Some solid-earth e-Science/Grid projects • GEON • NSF “Cyberinfrastructure” • EarthByte • Sydney University/Caltech/CSIRO • APAC Geosciences • Australian Partnership for Advanced Computing • pmd*CRC • Cooperative Research Centre for Predictive Mineral Exploration Cox/2005 AGU Spring

  5. pmd*CRC - geologic process simulations Archives Data Service Cox/2005 AGU Spring

  6. Status quo: Different formats and standards Proprietary Software Versions of Software User Data Structures Cox/2005 AGU Spring

  7. private  public boundary WFS Server WFS Client HTML GML • Data-source organised for custodian’s requirements • Community-specific GML application language • TigerGML, LandGML, O&M, XMML, CGI-GML, ADX, GPML, CSML, MarineXML etc Open Geospatial Consortium - Web Feature Service Cox/2005 AGU Spring

  8. WFS Server B WFS Server WFS Client WFS Server C Standard transfer format allows multiple data sources Cox/2005 AGU Spring

  9. Same format and standards XMML User XMML GML for geochemistry: XMML and OGC O&M XMML Cox/2005 AGU Spring

  10. XMML data packet • <GeochemMeasurement gml:id="WA_1_139459_Ag"> • <om:eventTime xsi:nil="true"/> • <om:eventLocation xlink:href="urn:x-seegrid:feature:xmml:GeochemSpecimen:WA_1_139459/location"/> • <om:responsible xlink:href="urn:x-seegrid:person:wyb123"/> • <om:procedureUsed> • <AssayProcedure gml:id="ICPMS_1_139459_Ag"> • <gml:name>Inductively coupled mass spectrometry</gml:name> • <om:method>ICPMS</om:method> • <analyteDetails> • <AnalyteSensitivity> • <analyte>Ag</analyte> • <lowerDetectionLimit uom="ppm">0.01</lowerDetectionLimit> • </AnalyteSensitivity> • </analyteDetails> • </AssayProcedure> • </om:procedureUsed> • <om:target xlink:href="urn:x-seegrid:feature:xmml:GeochemSpecimen:WA_1_139459"/> • <om:result relativeMeasure="lessThan" uom="1">1.e-8</om:result> • <analyte>Ag</analyte> • </GeochemMeasurement> All this (and more) required to properly transmit one number!

  13. One service – many uses GML-based data can be …. Rendered into a queryable map … … formatted into a report or …. Condition: community-standard data model/encoding … read and used by any WFS/GML enabled application Cox/2005 AGU Spring

  15. classic geophysics “Coverage” viewpoint classic geology “Feature” viewpoint Fields vs. objects • simple data structures • collated/gridded ready for analysis • netCDF, HDF-EOS • complex data • database insertion • complete feature interpretations • XML documents Cox/2005 AGU Spring

  16. Key Points • e-Science depends on • Informational Services – to supply modelling constraints • Computational Services – to supply simulators and solvers • e-Science community focus on “Grid” services • high-performance computing, PDE solvers – remote but tight connections • large datasets, data warehouses – simple data structures • Geospatial community working on REST web-services • loosely-coupled, decision-support– on-demand discovery, binding and chaining, • detailed semantics – complex data-structures, community schemas Cox/2005 AGU Spring
