Right Now you are asking yourself,
What does it detect?
![Page 14: Fusion Center Workshop and Table Top Exercisepesforum.org/docs/2018/VIIRS_Baldin.pdf · 01.11.2014 · 1-2 August 2018 Fusion Center Workshop and Table Top Exercise 3 Officer Gentleman](https://reader030.vdocuments.us/reader030/viewer/2022041223/5e0dd0b8a872a1652412c008/html5/thumbnails/14.jpg)

How does all this work?
Boats in Java Sea
Jakarta
The VIIRS day/night band (DNB) sensor detects lights present at the Earth’s surface, including those from boats.
![Page 18: Fusion Center Workshop and Table Top Exercisepesforum.org/docs/2018/VIIRS_Baldin.pdf · 01.11.2014 · 1-2 August 2018 Fusion Center Workshop and Table Top Exercise 3 Officer Gentleman](https://reader030.vdocuments.us/reader030/viewer/2022041223/5e0dd0b8a872a1652412c008/html5/thumbnails/18.jpg)
The VIIRS data is processed through Algorithms, output points are generated, and a vast data volume reduction occurs.

How does VMS and VBD matching work?
• Ingest VMS into VDB data.• Predict the location of VMS boats at the
time of the VIIRS overpass.• Identify three categories:
• VMS plus VBD• VMS only• VBD only

What’s the point?VMS & VBD can ID possible illegal fishing
• Most small boats stay relatively close to major landing sites.
• Only larger boats are able to reach the farther flung areas of the Indonesia EEZ.
• In areas such as the Northern Natuna Sea and Eastern Arufura Sea it is possible to identify potentially illegal boats by combining the VMS with VBD.
• The suspect boats are detected by VIIRS, but lack VMS.

Questions to Ask
45
• Are fishing fleets using lights in accordance to local regulations?
• Are they exceeding wattage? (16,000 watts in Indonesia)
• What type of fishing is occurring and where?
![Page 43: Fusion Center Workshop and Table Top Exercisepesforum.org/docs/2018/VIIRS_Baldin.pdf · 01.11.2014 · 1-2 August 2018 Fusion Center Workshop and Table Top Exercise 3 Officer Gentleman](https://reader030.vdocuments.us/reader030/viewer/2022041223/5e0dd0b8a872a1652412c008/html5/thumbnails/43.jpg)
Fishery Monitoring Options
• Set up email alerts for detections in:• Marine Protected Areas (MPAs)• No take zones• Seasonal fishery closures• Restricted coast waters
• Detect boats exceeding wattage limits.• Detect fishing boat clusters straddling EEZ
boundaries.• Cross reference VMS and AIS tracks to
identify “dark” vessels.

Plans for the coming year
• A second VIIRS will be launched this year. For some period of time two will operate, with a 50 minute offset. This could be used to ID stationary boats vs. drifters.
• Calibration testing to define detection limits and estimate wattage:• Based on long term records of VMS boats with known installed lighting. 51
surveyed boats.• The same approach could be applied to GPS & AIS tracks.• How? Collect VIIRS data on string of lights deployed at isolated locations.
• Improve the definition of recurring detections and validate the causes (FADs? Platforms? Fishing boat villages? Trans-shipment?).
• Define and characterize fishing grounds based on annual VMS & VBD data.
• Implement near-real time VMS / VBD cross matching.• Integrate into SeaVision.

Limitations
• Not all fishing boats are lit sufficiently for detection.• Some of the detected boats are not fishing boats. • These data provide no direct information on the
ownership of the detected boats.• Detection is in a single spectral band. Therefore it is
not possible to distinguish different types of lighting based on spectral signatures.
• In general, it is not possible to track individual boats through time.
• The current algorithm works best under low lunar illuminance. Detection thresholds rise under moonlit conditions.
