3.2. Navigation

The map can be explored by using the navigation tools available on the tool bar or from the Map menu.

• The ZoomIn tool enlarges a region of the map. Clicking once on the map will double the magnification and center the map on the point that was clicked. Clicking and dragging selects a region that will be enlarged to fit the window.

• The ZoomOut tool shrinks the map so that a larger region is visible. A single click reduces the magnification by a factor of two. Clicking and dragging selects a box such that the current contents of the window will be scaled to fit into that box.

• The Pan tool allows the user to move the map around by clicking and dragging.

• The Full Extent tool rescales the viewable region so that the entire map is visible.

• The Full Layer Extent tool rescales the viewable region so that the currently selected layer fits within the window. If no layer is selected this button will be disabled.

• The Full Shape Extent tool rescales the viewable region so that the currently selected shape fits within the window. If the shape is a point, it is centered and the map is zoomed all the way in. If no shape is selected this button will be disabled. This feature is especially helpful when identifying an object related to a selected record in a tableview (see below).
