The SCEDC has developed an improved Station Information System (SIS) for the Southern California Seismic Network (SCSN). This system has been the source of station metadata for the SCSN/SCEDC since September 2006. Updates of any field work resulting in a response change are distributed to SCEDC applications and users within 24 hours.

Scope: The Station Information System used by the SCEDC and SCSN has the following capabilities:
- Provides accurate station/channel information for active stations to the SCSN real-time processing system.
- Provides accurate station/channel information for active and historic stations that have parametric data at the SCEDC e.g., for users retrieving data via STP from the SCEDC or for analysts post processing events.
- Provides all necessary information to generate dataless SEED volumes for active and historic stations that have data at the SCEDC.
- Provides all necessary information to generate COSMOS V0 metadata information.
- Is updated through a graphical interface that is designed to minimize editing mistakes.
- Allows stations to be added to the system with a minimum, but incomplete set of information using predefined defaults that can be easily updated as more information becomes available. This aspect of the system becomes increasingly important with historic data when some aspects of the meta-data are simply not known.
- Facilitate statewide metadata exchange for both real-time processing and provide a common approach to CISN historic station metadata.
