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 objects identified by VIIRS.
  • Fishing Effort
    • Country: To filter AIS fishing effort data by country (flag state), choose the country or countries that you would like to view.
  • Indonesian VMS Fishing Activity
    • Registered gear type: To filter Indonesian VMS activity by gear type, select the types of gear you are interested in from the dropdown menu.
  • Peruvian VMS Fishing Activity
    • Registered gear type: To filter Peruvian VMS fishing activity by gear type, select the types of gear you are interested in from the dropdown menu.
