terraCatalog - Web Catalogue Service for Spatial Data Infrastructures
terraCatalog is a powerful and scalable metadata management system based on open standards, enabling the capture and serving of metadata for geo-resources. As an easy-to-use search engine on the Intranet and Internet, terraCatalog enables quick access to distributed geographic information resources within public or enterprise-wide spatial data infrastructures.
tterraCatalog supports the search for, and maintenance of metadata via intuitive web interfaces. As well as making locally-stored and managed metadata available to users via standardised interfaces, terraCatalog’s broker function enables it to integrate external catalogues and data sources in its search for metadata (distributed searching and harvesting). The system implements the OGC CSW 2.0.2 interface, as well as the ISO Metadata Application Profile V1.0 (ISO19115/19119) and the DE Profile for Catalogue Services.
Product Option: Distributed Search
The Distributed Search Option for terraCatalog provides the ability to include external catalogues into metadata searches. Once configured, searches will run against the local and remote catalogues in parallel, and the results will be displayed as a single search. The source of the metadata will be indicated in the results to give users an indication of where the data is coming from.
Product Option: Statistics
With the help of the terraCatalog statistical option, administrators can easily answer the questions "What is wanted?" and "What is used?". On one hand information on the polling frequency of the different metadata records created and stored in a sorted list. In addition, the administrator can have a ranking of the keywords entered and receive an overview of the most frequently searched terms. This provides opportunity to use the contents of the catalog to measure and manage demand for services and underpinning infrastructures.
Product Option: Harvesting
This Product Option adds the ability to conduct the recording of metadata documents in an automatic process when importing metadata.
At regular intervals, predefined data sources are checked and uploaded (generally by way of metadata documents that are accessible by http) and validated. If successful, the data is then published in the catalogue (with the visibility status ‘public’). When using automatic harvesting, transformations can be performed with stylesheets.
Product-Option:
terraCatalog-Connector for ArcGIS
With the terraCatalog Connector for ArcGIS product option, users can directly access discovered services and open them in ArcMap. In addition, many alternative map viewer and portal client connections are available that allow the direct transfer and visualization of the retrieved map services.
