ANAVnet - Navigational Warnings and Temporary Notices to Mariners (in force)

This geospatial dataset compiles the Navigational Warnings (coastal and local) and the Temporary Notices to Mariners that are currently in force and made available by the Hydrographic Institute through the ANAVnet service (https://geoanavnet.hidrografico.pt/).

Navigational warnings consist of messages containing urgent and vital information for the safety of maritime navigation, transmitted to ships in accordance with the provisions of the International Convention for the Safety of Life at Sea (SOLAS). Depending on the area for which they are issued, they may include:

Coastal Warnings (nav_warning_coastal): issued by a national coordinator and broadcast internationally through NAVTEX and/or Enhanced Group Call (EGC) systems;

Local Warnings (nav_warning_local): relating to inland waters or areas under the jurisdiction of port or maritime authorities.

Within the scope of Maritime Safety, there are also periodic groups issued by the Hydrographic Institute, known as Notices to Mariners (NtM). These are intended to disseminate important information for navigation safety and are also used to correct nautical documents. In this case, only Temporary Notices to Mariners (notice_mariners) are available: notices that report events of interest to mariners of a temporary nature, resulting from accidental situations or planned interventions, with a temporary impact on navigation safety.

The data provided here do not follow the S-100/S-124 model, corresponding instead to traditional Maritime Safety Information (MSI) messages, as defined within the framework of the Global Maritime Distress and Safety System (GMDSS).

This dataset integrates the High Value Data Sets/HVDs identified in accordance with Implementing Regulation No 2023/138 of Directive (EU) 2019/1024 on open data and reuse of public sector information.
