Description

SeisView program shows seismic data in SEG-Y format on screen of your personal computer (Windows-9X, NT, 2000, XP).

• supports standard integer (2,4 bytes) and IBM float (4 bytes) sample formats
• and nonstandard integer(1 byte), float IEEE (4 bytes) sample formats[2]
• shows seismic in various modes (wiggle, variable area, variable density, color)
• scaling seismic image, gain control, axes labeling setup
• plots seismic to printer (plotter)
• exports the image in Windows Bitmap (.bmp) and PostScript formats.
• SEG-Y headers browsing
• text header editor
• band pass filter
• automatic gain control
• header sequence consistency check
• selection of traces to be displayed by trace index or header value
• write whole SEG-Y file or part of it to disk in SEG-Y (IBM-32) format with ability to select data on base of trace index or trace header value and given time interval
• trace shift according with "Delay Recording Time" trace header value
