ISO advantages over CSDGM • Controlled vocabularies- Code Lists • Multi-lingual • Granularity • Feature level metadata
FGDCContent Standard for Digital Geospatial Metadata Metadata content: • identification: Developer, purpose, • quality: processes, methods, accuracy • geography and spatial and temporal schema • spatial reference,and • distribution of digital geographic data.
