Zoom to Last Extent of the Map

1. In the Toolbar place your mouse over the zoom last icon and a small pop-up message will tell you the function of the tool.

2. Click the icon. The Interactive Map will zoom to its previous extent. For example, your Interactive Map is zoomed to the scale of Polk County and then you pan the map to Jasper County. If you click the Zoom to Last Extent button your Interactive Map will zoom back to the Polk County extent.
