Checking this option will display a map marker at tracked location points. Click on a marker for more information at each location. If there are too many locations to map at once, a subset are displayed based on the current map view and your selected criteria: maximum number allowable, selection method, date range, and time range. To view all tracked locations, use the animation tools below to navigate through time.
In addition to markers, this overlay displays a line between successive tracked location points with arrows showing the direction of motion. This may help show the motion of an object over time, especially between disparate locations.
warning: Lines connect successive location points "as the crow flies" (by the shortest and most direct route): they do not skirt land, water, or follow coastlines as the tracked object may in actuality. For instance, a dolphin would not cross an island to reach the opposite coast! As such, these lines are for illustrative purposes only.
