The Skylight web platform offers a few ways to limit information displayed on the main map.

Each tab provides information on any applied settings:

• Events - Numbers of events enabled (e.g., 3 events enabled)
• Filters - Total number of filters applied (e.g., 2 filters applied)
• Date - Total date range available on the map and using the time slider (e.g., 48 hours of data available to the map)

Events

The Events tab let's you turn on/off any desired events. This includes any AIS-based events (e.g., fishing) and any Vessel Detection events.

Filters

Under the “Filters” tab, first select the filters you want to apply to the map. 

Filters are organized into two sub-sections:

Vessel Information (AIS / GFW)
These filters use AIS or GFW data to refine Skylight events based on specific vessel attributes, such as vessel type, flag, MMSI, and more.

IMPORTANT: Applying any of these filters will exclude all dark vessel detections. This is because all Event filters rely on AIS data, while dark vessel detections do not have associated AIS information.

Vessel Detections
These filters allow you to select the type of remote sensing used (e.g., Satellite Radar or Optical Imagery) or to isolate dark vessels from all vessel detections.

Events and filters can be saved for regular use as well as used as alerts. See the Saved Alerts section.

Once you have selected a set of filters, choose the specific criteria within each filter that you want to apply.

Date range and Time Slider

The date range filter is by default set to 48 hours (with 24 hours of events visible on the map using the time slider). Data is available up to 18 months in the past. Up to 31 days of data can be viewed at one time. 

The Time Slider can further manipulate the time range of what's visible on the map.
