light green is background, blue is water, dark green is parks/refuges/
forests, black lines are highways, red lines are interstates/
controlled access roads, dashed lines are railroads, yellow areas are
city limits.

Hi,

Can I ask how you created/plotted the grey dotted rectangular box on
the map? I am guessing its the search area of that particular
aircraft?

Was it a tracker device in the aircraft flying in that pattern, or was
it a "man-made" object?

thanks
bernard
