This data was acquired by a moving vessel. The timetag
was always recorded but the not the coordinates. So as the vessel speed is not constant I will have always will have deltas in the interpolation.

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
