The Searchable Product Depository (SPUD) is the IRIS DMC's primary data
product management system. Complementing the DMC's SEED and assembled
data archives, which contain time series recordings, the SPUD system
primarily contains derivative data products of other types (images,
movies, etc.) created either at the DMC or by members of the community.
For users SPUD is the query and access point for these products. The
web interfaces allow users to search for products using customized queries
across product and event details. Users can search across all product
types at once or within specific product types. SPUD also has web service
interfaces for programmatic discovery and access to the data products.
If any products from SPUD are used in your research please be sure to cite
the identified author of the product and the IRIS DMS
