CONVERSION PROGRAM PACKAGE FOR SEISMOLOGICAL DIGITAL DATA FORMATS ON PCS

A package of 17 conversion and 6 utility programs for seismological di gital data handling on PCs was implemented, One category of conversion programs can adapt user data from many commercially available acquisi tion software (on PCs or not) to many also commercially available proc essing software, such as IASPEI-software, SEIS89, SWS, or PITSA; the o ther category of these programs can convert between different formats used by well-known processing and analysis programs. A core-format for this program package was selected and the utility programs can perfor m the following tasks preserving the core-format: automatic detection of a missing component, reordering of components, extracting given cha nnels, resampling and filtering, and merging more files into a single file.
