Not all fishing boats are lit enough to be detected.
• The classic detection case is for boats using lights to aPract catch.
• Other fishing boats may be detected while lighting their decks for
safety reasons during operations.
• Not all the detections are from fishing boats. In some places VIIRS
appears to be detecting other types of boats that are well lit, such
as pleasure cruise ships or freighters?
• A valida-on effort will be required to determine:
– What types of boats are detected.
– What types of boats are not detected.
– Accuracy of boat counts.
– Whether boat type or size can be discerned based on brightness of the
lights.
