community to contribute to the interoperability in
geodata and operations(Buehler et al, 1996)
• Since 1994
• More than 20 SIGs /WGs
• 16 Abstract Specifications
– Central themes
• Sharing Geospatial Information
• Providing Geospatial Services
• 7 Implementation Specifications
• Legal liaison with ISO/TC211
