Mapping Tutorial: Zoom and Navigation
Navigation Map
The navigation map allows you to move around the main map in different ways. It also provides a landmark when the zoom rate is greater than 100%.
Whenever you click on the USA tab, you can change the zoom level from 100 to 1500% or more, by dragging the vertical cursor bar up or down or by clicking on the or buttons. You can also move the viewfinder with the mouse, or change its size by dragging the corners. Any such action is immediately transferred to the main map.
Whenever you click on the zooms tab, it is also possible to zoom in automatically, by clicking on one of the pre-defined zones (State).
Navigation Tools
The tools for moving around inside the map are in the first section, on the left-hand side of the toolbar.
Zoom: click-drag with the mouse to zoom in graphically. Click on the icon, then click-drag on the zone that you wish to enlarge. See also the navigation map section above.
If the mouse has a scroll wheel, this will allow you to zoom in and out.
Move map: click-drag with the mouse to move around inside the map. Click on the icon, then click-drag on the map to move in the desired direction. Using this button is optional; you can move around the map just with a click-and-drag.
Reframe: returns to the initial extent of the map. After zooming or moving around, click on the icon to return to the initial view of the map.
Search: locate a geographic unit by typing in its name or part of its name. Click on the icon, type in the name or part of the name of the geographic unit you wish to locate, and then click on Search. A list of geographic units containing the search term will appear. Choose the geographic unit that you wish to see on the map from this list.
