What are the filters and how do I use them?

Filters are created using the Filters tab in the map toolbox. Each layer has unique attributes that can be used for filtering to see a subset of fishing activity. Some of the filters that can be found are: Night Light Vessel Detections Radiance range: Higher radiance ranges correspond to higher confidence detections. Detection type: Options represent likely [...]

How do I view different types of data? (AIS, VMS, VIIRS)

To view different types of fishing vessel data, click on Layers in the toolbox, then Activity layers. You will have options of our different types of fishing activity to select from and can also customize colors of each layer. Learn more about the AIS and VMS layers in this video or this guide and about the VIIRS [...]

How do I search for a specific vessel?

First, you must be logged into your Global Fishing Watch account to search for a vessel. Click on the Vessels tab in the toolbox to the right and enter the vessel identifying information (vessel name, MMSI number, IMO number and callsign) in the search bar. Make sure that the activity layer you are searching the [...]

What do we mean by fishing activity?

Every broadcast AIS and VMS position that we receive from a fishing vessel is classified by the Global Fishing Watch fishing detection algorithm as either likely fishing or non-fishing. This classification takes into account the vessels movement in the days before and after the broadcast position as well as other information we have on the [...]

What is Global Fishing Watch’s VMS transparency initiative?

Transparency is crucial for good stewardship of our global ocean - to fight illegal fishing, to protect fish stocks and livelihoods and to increase the safety and well-being of fishers. If countries publicly share their fishing vessel monitoring data, then we can create a more complete and connected picture of global fishing activity. Global Fishing [...]

What is AIS?

AIS (Automatic Identification System) is a system that transmits a ship’s position so that other ships are aware of its position, to avoid collision. The International Maritime Organization (IMO) mandates the use of AIS in vessels larger than 300 gross tonnes that travel internationally. Many national governments have mandated vessels that fall outside the IMO [...]

What are the different vessel tracking systems out there and how can they be used together?

There are two general types of vessel tracking systems – transmitters and loggers. Transmitters use satellite tracking to continuously transmit vessel locations. The Automatic Identification System (AIS) and Vessel Monitoring System (VMS) are both transmitters. Loggers record location and transmit later. Lots of new technologies are continuously being developed. These include spot trackers with satellite [...]
