AIS-based vessel behavior events | ||
| Standard Rendezvous |

Fishing activity (e.g., trawling, long lining, purse seining, squid jigging). |
| Entry* |
|
User configured entry of a vessel (first AIS signal received) within a single Area of Interest |
| Speed Range* |
|
User configured speed detection by time or distance within a single Area of Interest |
|
Vessel Detections Black icons ( | ||
| Night Lights |
|
Ability to detect vessels using bright lights. Globally available nightly, but not effective where clouds and moonlight limit visibility. |
| Satellite Radar |
|
Vessel detections best suited for vessels constructed of metal. Clouds or other weather does not affect detection ability. |
| Radio Frequency |
|
Ability to detect vessels using onboard navigational radar. Not affected by clouds or other weather. |
| Optical Imagery |
|
Imagery capable of detecting vessels, including smaller vessels in optimal conditions (clear skies) |
) indicate a detection that is correlated to AIS.
