propduffer/pontius. the airway passing through the circle is N571 and the airway below it is B466. the dots look to me to be man-made. each one is accompanied by a label and where many labels are close to each other, they overlap and appear to cause the green "track "effect. the labels appear to have 5 characters, and they appear to be different for each dot. the only one I can make out ends in - - - TA. possible that dots represent received aircraft blips and MAF have appended a label to each one... pity label for the long arrow pointing to "track" is obscured by someone's camera...
