The Navigation Toolbox

The Navigation Toolbox (Figure 1) is where you’ll find resources to help you find your way around the map and perform measuring and magnifying operations.

Zoom In
Use the Zoom In tool to click on a certain location on the map to zoom in. Or, click and hold the mouse button to drag a box that will define a particular zoom extent.
Zoom Out
Zoom Out
To zoom out on a map, select the Zoom Out tool. Define the extent of the area that you wish to zoom out to by clicking on a location or by dragging a box to define a particular zoom extent.

Helpful Hint:  There are also ways of zooming in and out without using the Zoom tools. By dragging the handle on the Scale Slider located in the upper left corner of your Map Window. Move the handle towards the plus or minus sign to zoom in or out on the map, or simply click the plus or minus signs to zoom in or out with set increments.
Pan
Pan
The Pan tool lets you navigate around the map. Use the Pan tool by clicking and dragging the mouse on the map to reveal different areas. The area of the map that you grab will end up wherever you release the mouse button. For example, if you want to move North (up the map), click and hold near the top and drag the map down.
Helpful Hint  Alternatively, you can use the Navigation Control (located in the upper corner of the map window) to pan without switching to the Pan tool. Single-click on a directional arrow to have the map shift incrementally in that direction. You can also press and hold the mouse button on the Navigation Control and move the mouse over different directional arrows to navigate around the map. To stop scrolling, just release the mouse button.
Zoom to Full Extent
Zoom to Full Extent
The Zoom to Full Extent tool tool is a quick and easy way to zoom out as far as possible. Just click on the tool and the map will zoom out to its maximum extent. This is especially useful when you want to start fresh without losing the changes you made to the map.

Identify
Choose the Identify tool to select a feature and see a list of its attributes. Once the layer you are selecting features from is active, click on the feature you want information about. The attribute report will appear in the Selection Report window.
Measure
Measure
The Measure tool allows you to measure points (coordinates), lines (distances), and polygons (areas) on your map. There are three types of measuring tools located in the Measure dialogue box (Figure 2.1.2).

1. Measure Coordinates
The Measure Coordinates map function (Figure 3) allows you to click on the map to return the coordinate location of a particular point. The coordinates will be displayed in the Measure Window.

2. Measure Distance
The Measure Distance map function (Figure 4) enables you to measure distances on the map. You can measure the distance between two locations, or you can measure the total distance of a route with multiple stops. Click on the desired starting point and add another node by clicking on a different location to complete one line segment. The distance between the two nodes will be shown in the Measure Window, along with the total length of the line. If you are interested in the length of a line with multiple stops (more nodes), simply keep adding nodes. The segment length shown will always refer to the most recent segment. To change the unit of measurement, use the drop-down menu in the Measure Window.

3. Measure Area
The Measure Area tool (Figure 5) is another handy tool that lets you calculate the area inside a polygon. Use the Measure Area tool to define the vertices (corners) of a polygon by clicking on the map. The tool requires that you specify a minimum of three vertices before an area can be calculated. Add as many vertices as you need to accurately represent the area you want to measure. The calculated area is returned in the Measure Window along with the perimeter of the polygon. If necessary, change the unit of measurement with the drop-down menus provided.

Magnify
When you click on the Magnify tool, a magnifying window (Figure 6) will appear on your map. Click and hold the mouse on the grey bar at the top of the Magnifier to drag the window over a desired location. You can change the degree of magnification by using the drop-down menu at the bottom of the window. Note that when you change the magnification, the current map is not simply enlarged. Rather, new map data is retrieved and displayed, often showing new features that weren’t visible at the smaller scale.

Map Back
Clicking on the Map Back tool will return your map to the previously defined visible extent. For example, a user who is currently viewing the map extent at a scale of 1:250000 zooms into 1:100000, clicking the Map Back button will return the user to their previous scale (1:250000).

Map Forward
If you have used the Map Back button, clicking on the Map Forward tool will return the map to the next defined visible extent.
