Geospatial metadata and an ontology for water observations data
Work has been successfully performed by the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) to synthesize the nation’s hydrologic data. Through the building of a national Hydrologic Information System, the organization has demonstrated a successful structure which promotes data sharing. While data access has been improved by the work completed thus far, the resources available for discovering relevant datasets are still lacking. In order to improve data discovery among existing data services, a model for the storage and organization of metadata has been created. This includes the creation of an aggregated table of relevant metadata from any number of sources, called a Master SeriesCatalog. Using this table, data layers are easily organized based on themes, therefore simplifying data discovery based on concepts.
