  8. ISO/TC 211 statistics • 30 countries active members (P-members), • 24 observing members (O-members) • 18 external liaisons (organisations) • 10 internal liaisons (ISO) • More than 500 persons involved since start • 12 plenary meetings have been convened in 11 different countries on 5 continents NB! Figures are approximate and vary over time

  9. WG 2 - Geospatial models and operators WG 2 Antony Cooper CSIR - ICOMTEK South Africa • ISO 19107 - Spatial schema • ISO 19108 - Temporal schema • ISO 19109 - Rules for application schema • ISO 19123 - Schema for coverage geometry and functions

  10. ISO 19108 - Temporal schema Based on existing standards • ISO 31-1:1992 Quantities and Units • ISO 1000:1992 SI units and recommendations • ISO 8601:1988 Data element and interchange formats • ISO 11404:1996 Information technology – Language independent data types
