2.	Type an end location in the Location 2 field and press the Return key, or also select it from the list.

The distance between the two selected locations is shown above the Navigation Map.
Below each Location field you can see the latitude and longitude of the selected location.
The selected locations are marked on the globe and the Navigation Map. The globe rotates to center the locations, and a line is plotted between the markers on the Navigation Map.

The Distance Calculator can also show the distance between a location you have selected and a place where you position your pointer on the Navigation Map.
Working with the Navigation Map and the Flat Map The map located at the bottom of the Distance Calculator window is the Navigation Map. You can use this map to select locations by their latitude and longitude. Using the Navigation Map you can also switch to a large map view.
