Data Quality Control

The NCEDC developed a GUI-based state-driven system CalQC to facilitate the quality control processing that is applied to the continuously archived data sets at the NCEDC.

The quality control procedures for these datasets include the following tasks:

CalQC uses previously developed programs to perform each function, but it provides a graphical point-and-click interface to automate these procedures, and to provide the analyst with a record of when each process was started, whether it executed correctly, and whether the analyst has indicated that a step has been completed. CalQC is used to process all data from the BDSN network, and all continuous data from the NCSN, UNR, SCSN, and HRSN networks that are archived by the NCEDC.
