Zoom In Tool

This tool allows you to zoom in on a point that you pick. Click on the zoom in tool then click on the location you would like to zoom in on. The map zooms in and has its center on the spot you clicked.  You may also zoom in by drawing a box on the map with your mouse.  This redraws the map to the extent of the box.

Recenter Button

This tool allows you to recenter the map without zooming in or out. Click on the recenter tool then click on the spot where you want the center of your map to be. You can also move the map around by clicking on the arrows at the edge of the map.
