Discovery service disseminates a data source catalogue with descriptions of resources in the form of XML files. The metadata record is based on ISO 19115. The ODP service provides user interfaces for data and product search supported by the catalogue. The data source catalogue can be accessed from external systems directly or alternatively by reformatting into other metadata structures.
Viewing service is based on web‐ based application accessible via the web browser and provides:
• data search that defines the sampling criteria using a spatial region, time period, phenomena, platform, etc.;
• access to remote data sources via the Integration Server including request status monitoring; and
• processing of transport data files and tabular‐graphic and map visualization of data using standard forms.
Analysis service has been developed to provide near real-time GIS-layer generation from distributed datasets both with interactive and fast presentation of multidisciplinary data and products on a map. It also includes Web Map Services (WMS) as a viewing service for data representation on a map. The user can sdjust the composition of the map layers, the number of maps for viewing and other specifications.
The service enables a joint analysis of data to provide a view of the spatial variability of marine processes. ODP renders maps generated by the analysis service using Open Layers and MapServer.
Download service allows the user to download selected data to the local computer after viewing. If time scheduling is required to download data, the user can register the site for downloading, the list of required datasets and the sampling criteria. The transport data file formats that are available are:
• NetCDF ‐ E2E convention
Selected data can be either downloaded in a single zip‐file or viewed using the ODP result viewing service.
