The bottom option is an Inside-looking-out perspective. This view is from the

center of the map — this allows you to spin the map around you.

3. Use the Rotate controls to rotate the 3-D map to the new position.

The reference arrow points to the direction that you will be viewing on the map,

which varies depending on the 3-D View selection you made in step 2). The degree

of map rotation displays above the Rotate arrows. You can rotate the 3-D map using

one of the following methods:

• Press and hold the left arrow button to rotate the map clockwise.

• Press and hold the right arrow button to rotate the map counter-clockwise.

• Drag the square map in the Rotate graphic to the new position.

• Click anywhere on the square map in the Rotate graphic to move the map in

that direction.

• Click a directional letter (N, S, W, or E) to rotate the map in that direction.

• Click the brown area that surrounds the square map to rotate the map in that

direction.

4. Use the Pitch controls to change the pitch of the 3-D map.

The pitch range depends on the terrain. 90° looks straight up, -90° looks straight

down, and 0° is horizontal.

You can control the pitch using one of the following methods:

• Press and hold the up arrow to increase the pitch.

• Press and hold the down arrow to decrease the pitch.

• Drag the reference arrow to the new pitch.

• Click anywhere on the graphic to update the pitch.

5. If you selected the Outside-looking-in perspective, you can adjust the distance from

the map center using the Distance up/down buttons, by clicking the Distance

graphic at the distance you want or by dragging the numeric distance display in the

Distance graphic.

If you selected the Inside-looking-out perspective, you can adjust the elevation of

the view over the 3-D map using the Elevation up/down buttons, by clicking the

Elevation graphic at the elevation, or by dragging the numeric elevation display in

the Elevation graphic.

Note Elevation indicates the height above terrain, not the height above sea level.

6. To pan the 3-D map and simulate a fly-over, drag the circle in the Pan graphic in the

direction you want.

7. Click Hide 3-D when finished.

The map changes to a 2-D view.

Select 2-D from the drop-down list at the top of the left map window when finished.

Tips

• When the 3-D map window is open, you can use the grab and pan tool

on the

toolbar, Compass Rose

navigation tools, zoom tools, and/or the overview map

window to adjust the 3-D map.

• Scroll along the edges of the 2-D map or pan with the navigation tools to redraw the

2-D background; the 3-D map redraws with the new map center.

• Click a point on the 3-D map to center the map on that point.
