What is VIIRS?

What is VIIRS?
1

The Visible Infrared Imaging Radiometer Suite, or VIIRS, is a polar orbiting satellite that uses highly sensitive optical sensors to see lights at night. The Earth Observation Group (EOG) at the Colorado School of Mines maintains the VIIRs Boat Detection (VBD) database, which identifies vessels in the VIIRs data that use light to attract catch, such as most industrial squid vessels and some types of purse seines. Through a partnership with the Earth Observation Group, we are incorporating this database into our portals to supplement vessel tracking data—more than 85 percent of the fishing vessels in the VIIRS database do not broadcast AIS or VMS.
