Creating Start/Finish Lines in Google Earth Pro

You can create a track map for your Video VBOX  and VBOX Video unit in Google Earth Pro.

Adding paths in Google Earth Pro

To do this you must first find your track location.

With the track located, click on the Add Path button in the toolbar.

This will open an Edit Path pop-up window that will remain open while you trace the track outline.

Tip: You can move this window to the edge of the screen to make sure that you can still see the track image. This will simplify the process. 

Now you can start creating your path. Right-click on the map image to set the first sample point. Any subsequent points will be connected in the order they are drawn in.


  • You can select any point by clicking on it. When you have selected a point you can add more points, slotting them in between existing points.
  • You can delete a point by selecting it and pressing the delete key or right-clicking with the mouse.
Drawing the start/finish lines
  1. Click on a location before the start/finish line and drag to draw a line down the track leading up to, and crossing the start line in the direction you intend to drive across it.
    Keep the line as straight as possible to get the best possible heading values calculated and r
    elease the mouse button when you have crossed the start line by at least 10 points.
  2. Add two separate points that create a line along the start/finish line – see the example below.
  3. You can add a separate finish line or split points by adding more lines across the track in the desired positions. Repeat steps 1 and 2 for each line. You should add crossovers for each point to make it easily identifiable.

    The following image shows a start line, two split points 
    and a separate finish line.
  4. When you are happy with your lines, go to the Edit Path pop-up window that appeared when you clicked the Add Path button.
  5. Give your path a name in the Name: field.
  6. Click OK.
  7. The path file should now appear in the left-hand toolbar on Google Earth under Places.
Saving the SPL/DSF file

  2. Right-click it and select Save Place As... 

  3. Save it to the required location.

  7. Now you must set the start point. Click on the data graph to locate the cursor.
  8. Move the cursor to the crossover point on the path.

    Note: Using ALT + Arrow keys moves the cursor sample by sample. Once your cursor is sitting at the start point, press the space bar.
  9. A window will appear to show that the start line has been set and you will see a green dot on your map graph.
  10. If you need to add split points or a separate finish point, position the cursor in the next desired crossover position.

    Note: Press S to set split points and press Shift + Spacebar to set a separate finish.
  11. When you have set all the required points, click on Main Graph.
  12. Select Start / Finish / Split Lines and Save from the drop down lists.

  13. In the following pop-up window you can choose whether to save the file as a .SPL file or a .DSF file.

    Note: Video VBOX or VBOX
    Video units will accept either of these file types when they are loaded into a scene, but they can only accept a .DSF file on an SD card. PerformanceBox or DriftBox  units can only use .DSF files.
