Question 3

How do I download charts for offline use?

Henri · Accepted Answer

Download

In the Settings of NavimetriX, under the Geogarage Charts section, tap “Add New Zone”, then define the geographical area to download by dragging the green corners of the grey rectangle.

The Area selection dropdown menu offers two zoom-level options for the maximum chart scale:

11 (Offshore) — covers a large area containing only small-scale charts (ocean routes, offshore charts).
18 (All) — includes all scales up to detailed large-scale charts (ports and anchorages). If the selected area is too large, a warning will appear.

Once confirmed, a countdown shows the preparation and download progress.

A green frame remains visible so you can add new adjacent download zones without overlap using the “Add a new area” button. Only downloaded charts are available for offline use.

Updating downloaded charts

The downloaded chart zones are listed by publisher in the Geogarage Charts drawer. A checkbox allows you to select them for the Delete or Refresh functions.

Whenever a chart update is published by the provider, the Refresh button next to each zone becomes active. You can update them individually or in bulk by checking multiple boxes and pressing “Refresh Selected”.

Question 4

How to display AIS targets over Internet?

Francis · Accepted Answer

AIS targets over Internet come from the global AISHub network, to which NavimetriX is affiliated.

The coverage area is available on an interactive map.

The use and handling of AIS targets over Internet is exactly the same as for AIS targets received on board using an AIS receiver that transmits NMEA data to the application. For more details, see:

How to display AIS targets? in this FAQ.

Open the Settings panel (gear button at the top right)

Select the AIS option
Enable AIS over Internet

AIS targets via the Internet are represented **in blue**

Cautions:

AIS targets over Internet should be considered for informational purposes only. Time delays due to Internet transfer speeds make them unsuitable for navigational safety, whereas reception on board by a dedicated receiver is at VHF frequency in real time.

They are therefore represented by blue icons to differentiate them from green AIS targets icons received directly.

For more details, see: What do the icons displayed on the chart mean in this FAQ?
