    • The SACs-formatted waveform file is an extended SAC format for holding multi-channel of waveform data in a compact single file. The 1st 2 bytes integer expresses the number of channels, followed sequentially by the SAC head and waveform data of each channel. SACs can be converted to stabdard SAC files using GeoTaos_Map program.
    1) Drag and drop the SACs file to GeomapTaos_Map
    2) Active the working sheet at the right and upper side
    3) Sellect 5:- or 6:-comand from dropdown menu in row-5
    4) Click [Do..] button in row-5
