Observatory, the Princeton African Drought Monitor, the NIDIS Server, the University College
London drought monitor, and the Argentina SMN drought monitor make the functionality of the
GDMP possible.
In between the bottom rung (the sensor and model data sources of the observing system)
and the upper tier (and the OGC-supported web service data exchange over the WWW) are
additional layers which include controlled vocabularies, dictionaries, ontologies, semantic
mappings, and transfer format and protocols, along with common data models, for data
integration and processing this information at multiple levels, republishing the information in a
format immediately available for decision making. This functionality is depicted as schematic
boxes in Figure 8(a), but the actual operations are set out below.
This overall strategy is a scalable system that permits integration multiple data stores
(information hubs), along with information of multiple disciplines.
