The zoom category provides tools to aid in navigating within the map region.
| The Zoom In tool, default, is used to enlarge a portion of the map. Select this tool, then click and draw a box on the map around the area what you wish to see in more detail. Clicking without drawing a box, will zoom in with the center point where you clicked by a factor of 2.
|
| The Full Extent Zoom tool will zoom out to the starting/initial extent of the map. |
| The Zoom Out Tool is used to zoom out a portion of the map. The box drawn with this tool is used to
calculate a zoom out factor. A smaller box will zoom out more than a large box. Clicking without
drawing a box, will zoom out with the center point where you clicked by a factor of 2. |
| The Zoom to Region or Area tool allows you to zoom to a region, state, or locale. Click on the
tool, below the map region are drop down menus to choose a Region, State, or Locale. Once an area
is choosen, the map will automatically zoom to the location. |
| The Zoom to Previous Extent tool will change the extent to the last extent (like
an undo feature just for the zoom scale). |
| The Zoom to a Point tool allows you to enter a coordinate. Click on the tool and
a window will pop up. Enter coordinates, Longitude and Latitude in decimal degrees, then click
OK. The map will zoom in and center around the coordinates entered at a scale of
approximately 1:3,700,000. |
