Open a GPS Track in Google Earth Pro

Use this when

You want to view your sonar track in Google Earth Pro, overlay it with satellite imagery, or share the route with someone who does not have HumVision.

Before you start

• Open a recording in HumVision. The Export button is only active after a recording loads.
• Install Google Earth Pro if you have not already. It is free.
• The recording must have GPS data embedded. If the map tab shows no track, the recording has no usable GPS and there is nothing to export.

Export the KML file

1. Open a recording in HumVision.
2. Click Export in the viewer toolbar.
3. Click Export GPS Track (KML).
4. Choose a save location and click Save. HumVision writes a .kml file named gps-track.kml.

The KML file contains:

• A Sonar Track line showing the full boat path.
• A Contacts folder with any contacts you marked, each placed at its recorded depth and position.
• An Annotations folder with any annotations you added.

If you only need a plain track with no contacts or annotations, the GPX format also works with Google Earth Pro. Click Export GPS Track (GPX) instead and open the .gpx file the same way.

Open in Google Earth Pro

1. In Google Earth Pro, go to File > Open.
2. Select the .kml file you saved.
3. Click Open. The track appears under Temporary Places in the sidebar and the map flies to it.

To keep the track across sessions, right-click it in the sidebar and choose Save to My Places.

What you should see

Google Earth Pro draws the boat path as a blue line on the satellite basemap. Each contact appears as a blue target pin; each annotation appears as a small circle. Clicking a pin opens a pop-up with depth, classification, and any notes you added in HumVision.

If it does not work

• Export button is greyed out — No recording is loaded, or your account is in read-only mode. Load a recording first, or activate HumVision from the sidebar.
• "There is no GPS track to export" toast — The recording was captured without a GPS receiver, or the unit had no satellite lock. See Why GPS data may be missing.
• File opens but no track appears in Google Earth Pro — Confirm you saved a .kml file and not a .gpx. Google Earth Pro opens both, but double-check the file extension. If the track still does not appear, the recording may have had GPS coordinates at 0,0, which are filtered out as invalid.
• Track appears in the wrong location — The GPS coordinates recorded by the unit may have included a brief period of bad lock at the start of the session. The first and last few points are sometimes unreliable until the unit acquires a full fix.
