ISO/TC 211
Normative Statements & Conformance
This site provides URI dereferencing for normative statements, conformance classes, and conformance tests defined in ISO/TC 211 Geographic information/Geomatics standards. Every URI used in a published standard resolves to a page here.
Supported Standards
Each standard provides dereferenceable URIs for its requirements and conformance classes.

URI Dereferencing
ISO/TC 211 defines unique, persistent URIs for every provision statement and conformance test. This site resolves those URIs to structured pages.
