Before processing with BSU software, one must first convert the data to bsegy format. Later sections in this document give examples on how to do that conversion. Often, there will be two steps. Conversion of the data (using a program from the above list), along with a transfer of survey or “geometry” data to the headers. The need for this second “setting geometry” step is the common practice of not transferring survey information into the digital data. Either a format may not include options for this information, or it may be that so much was going on in the field that the observer was stressed and was lucky to just get it all down on “observer's logs”. These are paper sheets with the information about shot and receiver location, sample interval, etc.
In section 6.7.5, an example is presented for down-hole BISON data. You can download this data set from the same web site that you downloaded BSU. The Geologan data example illustrates both the conversion of the digital signals and the transfer of geometry to the BSEGY data set.
