Single Plot of all Surveys (default) - Tracklines of all surveys
identified by a Search will be displayed on one screen/page.
Separate Plots by Source - a separate screen/page will display surveys
from each source organization.
Separate Plots by Platform or Project - a separate screen/page for
each platform (i.e. ship) or Aeromagnetic Project
Separate Plots by Survey - a separate screen/page for each survey.
The lat/lon limits will be the same for all plots (i.e. either the limits
of the Search Criteria Area or if no Search Area was specified then the inclusive
limits of all surveys identified by the Search)
Separate Survey Plots (survey area limits) - a separate screen/page
for each survey. The lat/lon limits will be different for each plot (i.e.
restricted to the area of each survey).
