Welcome to this tutorial on how to use the SubTel Cable Map. My name is Kieran Clark, Lead Analyst at SubTel Forum, and by the end of this tutorial, you will be able to navigate and understand the visual and data elements of the interactive map.


Navigating around the map is easy, simply click and hold the left mouse button to pan around the map.

To zoom in and out, use your mouse wheel or the in-map zoom controls.

Data and Information

Now, let’s take a look at using and understanding the map’s data display features.

There are two features of the user interface to pay close attention to – the Data Pane  and the Information Pane.

Data and Information Panes

The Data Pane lists all the layers and map features. The Information Pane populates with data appropriate for the selected map feature.

The first feature is Layer Visibility. On the Data Pane, you can click the icon for a data layer to turn it on or off. Note that this does not apply to the “Countries” layer.

To navigate the Data Pane, click the name of a data layer to expand the full list of entries. I am selecting the In-Service Systems layer for this tutorial.

Expanded Layer List

Click an entry in the expanded layer list in the Data Pane to zoom to that feature.

Alternatively, you can also click any cable system line, landing point dot, data center icon or country to select the feature.

Once a feature is selected, the Information Pane will populate with the selection’s data.

To clear the selection, click “Clear” in the Information Pane. This will clear your currently selected map element.

If you select a feature that overlaps with others, a feature page count and navigation arrows will appear above the Information Pane.

Overlapping Map Features and Zoom To

Clicking “Zoom to” will automatically center the map’s view on the selected map feature.

Lastly, if you would like to submit an update to the cable map, click “Submit an update” in the center of the map header which will open an email link to me, directly.
