Changing the map size

Terrain Navigator offers two ways for you to change the size of a map and show more detail or area.

• Zooming: The toolbar has two icons bearing a magnifying glass: one with a plus sign and the other with a minus sign. When the plus sign magnifying glass is selected, you zoom in when you click the map. When the minus sign magnifying glass is selected, clicking zooms you out.
• Changing the scale: Maps can be displayed in either 1:24,000 (more detail, smaller area) or 1:100,000 scale (less detail, larger area). Note the map scale command in the toolbar that displays a menu for selecting the scale of your choice.
