The NavimetriX interface has been designed to be clear, intuitive, and quick to use, whether on a computer, tablet, or smartphone. Here is a complete description, section by section:

• • Routes

• • Routings

• • AIS targets

– Bottom left

• • Map scale

• • GRIB file loaded, for example :
    GFS 0.25° 20251007 00Z +384
    
    • • GFS model
    • • 0.25° grid, approximately 26 km
    • • published by NOAA on October 7, 2025
    • • Calculated at midnight UTC, we refer to the 0-hour run or 00Z.
    • • containing 384 hours from the 00Z run. If you see +36, this indicates that the first 36 hours of this GRIB file are from the 00Z run, while the following hours are from the previous run, which was the 18Z run on October 6. This gives you access to the latest data from the run without having to wait for the entire run to be calculated. For the GFS, this saves about 3 hours.

– Below: the Timeline

• • Displays all hours covered by the currently loaded GRIB file.

• • Each white dot on the time bar corresponds to a time step in the GRIB file.

• • The time displayed just above indicates the current position of the Timeline.

• • If you click/tap on this time, the Timeline will jump to “now” and the seconds will scroll by (letting you know that you are at the current time).

• • You can:
    
    • • Slide the Timeline with your finger or mouse,
    • • Click/tap on a location to move directly to a specific time.

• • The data in the GRIB file displayed is then that for the selected time.

• • If a routing is displayed, the boat moves at the selected time along its trajectory.
