Show Labels for Targets : Choose method for determining whether AIS labels are shown. When Off, labels are not shown unless the vessel is selected. When On, each AIS vessel is normally labeled with the vessel name.
When set to Auto labels are shown according to an algorithm to detect when the display is cluttered. For instance, vessels with SOG less than 2kn normally do not have labels shown.
For On and Auto, labels for certain vessel types (pilot, tug, towing, dredging, law enforcement, military, and rescue) are normally shown.
Show CPA on Labels (Only SEAiq Pilot) : When enabled and labels are visible, each AIS target within 10nm of Own-Ship is shown with its Closest Point of Approach (CPA).
CPA gives distances based on center of Own-Ship and target. This assumes vessels maintain course (COG & SOG), regardless of current ROT.
Show BCR on Labels (Only SEAiq Pilot) : When enabled and labels are visible, each AIS target within 10nm of Own-Ship is shown with Bow Crossing Range (BCR).
BCR gives distances for centers of Own-Ship and target, not their bow or stern. The calculation assumes vessels maintain (COG & SOG), regardless of the current ROT.
