Repeated surveys lines
If it is necessary to repeat a set of measurements on a survey line, you should take
certain precautions to ensure data handling is done in the most effective manner.
The ENVI-MAG recalls or outputs repeated data sequentially by time at the
same locations, resulting in unsightly (or unintelligible) recall displays. You will
also have to substantially edit your data files to properly use them with the
ENVIMAP software.
It is recommended that you assign a minor increment to the survey line
number prior to re-surveying to avoid problems. For example, if you are
about to re-survey line 40N, enter the line number as 40.1N instead.
