The edited shotpoint navigation was extracted from Delph Seismic, and each file was run through a filter to remove spurious data values. The files were then reformatted into ASCII text files, and the year and Julian day was manually entered into each record. Each file represents a separate trackline, with six fields separated by tabs. The links below provide access to the files by trackline number.
Field 1:Shotpoint Number
Field 2:Longitude (decimal degrees)
Field 3:Latitude (decimal degrees)
Field 4:Year
Field 5:Julian Day
Field 6: GMT (HR:MIN:SEC)
The edited shotpoint navigation files can also be located by going to the subfolder EDITNAV located inside the NAV folder at the top level of the DVD
. All the files are stored as flat ASCII files and have a .txt extension. (key9715a.txt)
