Monochrome Plot (default) - Black and white plot.
Color code by Source - tracklines of all surveys from each source
organization will have the same color.
Color code by Platform or Project - tracklines of all surveys from
each platform (i.e. ship) or Aeromagnetic
Project will have the same color.
Color code by Survey - the trackline of each survey will be a different
