AIS use conditions

Ship Tracking is an information service prepared for AIS data supplied through Pelyr. The map identifies the sources and licences of the data it displays. Positions and vessel details can be incomplete, delayed, inaccurate or absent.

• Do not rely on this service to navigate, avoid collisions, support search and rescue, protect people, property or the environment, or determine legal compliance. Use the appropriate official sources and equipment.
• Do not use it to surveil, harass or track individuals.
• Do not extract Pelyr-licensed positions in bulk, including through repeated requests. Do not export or redistribute them as raw data, a dataset, a feed or a position-report service.
• Do not relay, resell or share provider access, or expose provider credentials.
• Keep the source credits with any permitted use. Each displayed source retains its own licence.

This page offers no raw AIS download or feed relay. Provider credentials are kept private and are not supplied to website visitors.
