Unidata embarks on new projects to help make its data and tools available to a broader, more diverse audience. The following are a list of LDM-related projects between the Unidata Program Center and external collaborators.
The Unidata community of over 160 universities is building a system for disseminating near real-time earth observations via the Internet. Unlike other systems, which are based on data centers where the information can be accessed, Unidata Internet Data Distribution (IDD) is designed so a university can request that certain data sets be delivered to computers at their site as soon as they are available from the observing system. The IDD system also allows any site with access to specialized observations to inject the dataset into the IDD for delivery to other interested sites.
Unidata Local Data Manager (LDM) is a collection of cooperating programs that select, capture, manage, and distribute arbitrary data products. The system is designed for event-driven data distribution of the kind used in the Unidata Internet Data Distribution project.
