The GeoNetwork ConceptThe GeoNetwork Concept– ISO/DIS 19115
This new international standard defines the schema required for describing geographic information and services. It provides information about:
– identification;– extent;– quality;– spatial;– temporal schema;– spatial reference;– distribution …of digital geographic data.
The GeoNetwork ConceptThe GeoNetwork Concept– OpenGIS
GeoNetwork uses Open GIS Consortium (OGC) compliant map services for dynamic mapping. The OGC is a not-for-profit organization dedicated to the development of open geoprocessing systems and standards.
