Program to Convert SUDS2ASC Files to a Single Binary SEGY File

By Mark Goldman

This program, SUDS2SEGY, converts and combines ASCII files created using SUDS2ASC Version 2.60, to a single SEGY file.

SUDS2ASC has been used previously to create an ASCII file of three-component seismic data for an individual recording station. However, many seismic processing packages have difficulty reading in ASCII data. In addition, it may be cumbersome to process a separate file for each recording station, particularly if traces from different recording stations contain a different number of data samples and/or a different start time.

This new program - SUDS2SEGY - combines these recording station files into a single SEGY file. In addition, SUDS2SEGY normalizes the trace times so that each trace starts at a given time and consists of a fixed number of samples. This normalization allows seismic data from many different stations to be read in as a single "data gather". SUDS2SEGY also produces a report summarizing the offset and maximum absolute amplitude for each component in a station file. These data are output separately to an ASCII file and can be subsequently input to a plotting package.
