Abstract
Three public geospatial image catalog services, FGDC Clearinghouse, NASA ECHO and GMU CSISS CSW, were reviewed, considering the following aspects: metadata generation, metadata ingestion, catalog service conceptual schema, query protocols and system distribution. This review results show how it is becoming possible to query metadata holdings through public, standard Web-based query interfaces. It also show that the catalog service providers still must define a catalog service schema that meets their particular needs.
