Beaufort's Cooling Down

From the ice cold...

I nixed the idea of figuring out the X/Ys.  I loaded the nav files into SMT and loaded each SEG-Y separately.  Seems to look okay as you can see. The X/Ys now match up to the correct UTM Zone 6 numbers. Unfortunately the demo copy from SMT doesn't let you modify the SEG-Y in any significant way. You have no control over the EBCDIC, no options for the trace headers at all. Ho hum. I'll check back later with OpendTect.

I mean all you get is:

C 1 CLIENT COMPANY CREW NO

C 2 LINE WB-844_AMPLITUDESFIX MAP ID

C 3 REEL NO DAY-START OF REEL YEAR OBSERVER

C 4 SHOTPOINT: 5 LONG SHOTPOINT FOR 2D AND 3D SURVEY DATA

C 5 LINE NUMBER: 17 LONG LINE RECORD

C 6 TRACE NUMBER: 25 LONG TRACE RECORD(CDP Number)

C 7 SHOTPOINT: 21 LONG SHOTPOINT FOR ARBITRARY LINE

C 8 CDP_X: 73 LONG CDPBIN NUMBER

C 9 CDP_Y: 77 LONG CDPBIN NUMBER

C10 NSAMPLE: 115 UNSIGNED SHORT NUMBER OF SAMPLES

C11 SRATE: 117 UNSIGNED SHORT SAMPLE RATE

C12

Not much. Ho hum. It was free. Back to SeiSee.
