With a Geographic
Data Viewer map you can look at a specific area of interest. You
can move around the map using the pan tool. The Pan tool lets you slide
around to different parts of the map. Suppose you want to go north(up
the map). Grab the Pan tool and grab (press and hold down the mouse button)
onto the map and pull it down. Whatever part of the map you grab with
the little hand will end up where you let go of the mouse button. Just
like in real life. This works for moving any direction on the map.
The first is the Previous
Extent tool. This button jumps back to the previous map extent you were
at. If you want to go back to where you were three zoom-ins ago, press
it three times.
Another button is the
Zoom to Full Extent button. It zooms you out to the maximum extent of
the information.
The Zoom to Layer Extent
button zooms to the maximum extent of the active layer. Next you will
find out how to make a layer active.
