Explore GeoIndex maps with the
overview and magnifier

Overview

The Overview window displays a small map with a larger extent than the current map. The current map's extent is shown in this window with a red rectangle.

• Display the Overview window by clicking the overview icon in the navigation toolbar.
• As you zoom the map in or out, the Overview map's extent may change so it shows an area somewhat larger than the main map.

Magnifier

The Magnifier window allows a close-up view of a small portion of the main map.
