Authority of WIS Compliance Specifications
Existing centres within WMO Member States may apply for designation as one of the functional centres forming the core infrastructure of WIS: Global Information System Centres (GISCs) Data Collection or Production Centres (DCPCs) National Centres (NCs)
Designation requires a statement of compliance with required WIS functions, compiled by the Inter-Commission Coordination Group on WIS (ICG-WIS)
The approved WIS Compliance Specifications are the authoritative source for interoperable interfaces required of WIS GISCs, DCPCs, and NCs
