At the moment there is only setting concerning display of points on the map.

Draw Mapicon on Track
When displaying the route on the map, the recorded point is displayed with a yellow marker. Not all points are displayed depending on the magnification of the screen display.

This setting is effective only when "Draw Mapicon on Track" is turned on.

At the point on the map, the time when this point was recorded and the moving speed from the previous point are displayed. It is not displayed when the read log does not include information on the positioning time.

Maintain advanced information when saving the log to a file. If the saved logs are displayed in Google Earth, please turn off when the route gets stuck on the ground.
