The Zoom out tool allows the user to decrease the scale of the map -- that is, to get “farther” from the map and view a broader area in less detail.
To zoom out:
1. Select Zoom Out from the toolbar.
2. With your mouse click-and-drag to draw a box.
3. The map will recenter and zoom out where you dragged a box.
In the example below, a box is used to define the zoom out parameters. When a user clicks and drags to draw a box on the map, it will decrease the scale to a predefined amount and recenters to the location where user dragged the box.
