About SPUD

SPUD Version 3.0

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 [Citation Information].

About Film Chip Products

The USGS WWFC Pilot Scanning Project

The World Wide Standardized Seismograph Network (WWSSN) began operations in 1961. One hundred twenty stations were installed, covering every continent. A station consisted of 3 short-period and 3 long-period seismometers, recording apparatus, radio-synchronized crystal clock, and calibration controls.

Data were originally recorded on photographic paper, then later on heat sensitive paper. The original records were photographed at the WWSSN Data Center using 70 mm film and stored by station and year on a 70 x 120 mm film chip. Lamont-Doherty Earth Observatory and the USGS Albuquerque Seismological Laboratory (ASL) each hold near-complete film chip sets of the WWSSN data. The slow degradation of these film chips has prompted this pilot project in 1999.

The film chips are black and white and have been digitally scanned with a resolution of 3200 dpi. The image has been cropped to exclude areas on the film chip which do not contain the image of the original record, however in all cases, the final product contains all of the original photographed record. The resulting grey-scale images have been saved at approximately 1/10th of the original film chip size as TIF files and then compressed using gzip. Enlarging the images by a factor of 10 results in images similar in size to the original analog record.
