Zooming to a Specific Location or US Street Address (Zoom Goto Command)

You can use the Zoom Goto dialog box to zoom to a location, such as an airport, or to a US street address or ZIP code.

To display the Zoom Goto dialog box, click the Zoom Goto button on the toolbar, or right-click in the map and choose Zoom > Goto from the popup menu.

You can now do one of the following tasks.

To zoom to a location:

1. Click the Location tab, and then select a category from the Category list.
2. Type a location name to use as the center of the map, type the map width to display, and then click OK.

   You can enter just a portion of the name you are looking for. Autodesk MapGuide will return a list of places that contain the text you entered. For example, to find San Francisco, you could type "San" to receive a list of all places that begin with "San," and then choose San Francisco from the list.

   Note You specify the width in the current display units. If the location you're zooming to is a point or text feature, type the width of the area you want to display in the map window. If the location is not a point or text feature and you specify a width, the width setting will be ignored.

3. If the zoom location has an access key assigned to it, enter the access key. You will need to contact the author of the map if you do not know the access key.

To zoom to a street address or ZIP code:

1. Click the US Street Address tab (not available on all maps), and then enter a complete US street address (address, city, and state) or a ZIP code.

   

2. Type the map width to display, and then click OK.

   Note You specify the width in the current display units.

 
Zooming to a Map Width

You can zoom to a specific width in a map.

Note You specify the width in the current display units.

To zoom to a map width

1. Right-click in the map, and then choose Zoom > Width from the popup menu to display the Zoom Width dialog box.

   

2. Enter a value in the Zoom Width dialog box, and then click OK.

   The map zooms in or out to the width you specified, retaining the current center of the map.

 
Zooming to a Map Scale

You can specify the map scale to zoom to. Remember that the larger the second number in the scale ratio is, the more you will zoom out, so you will display a larger area with less detail. The smaller the second number is, the more you will zoom in, so you will display a smaller area with more detail.

To zoom to a map scale

1. Right-click in the map, and then choose Zoom > Scale from the popup menu to display the Zoom Scale dialog box.

   

2. In the text box, type the scale ratio you want to use. For example, to zoom to a scale of 1:200000, type 200000 in the text box.
3. Click OK.

   The map zooms in or out to the scale you specified, retaining the current center of the map.

 
Zooming In by a Magnification Factor of Two

You can click a point in the map to zoom in on that point.

To zoom in by a magnification factor of two

1. Click the Zoom button on the toolbar, or right-click in the map and choose Zoom > Zoom from the popup menu.
2. Click a point to be the center of the redrawn map.

   The map zooms in on the point you clicked to display the map at twice the previous magnification.

   You can continue to zoom in by clicking another point in the map.

   You can continue by zooming in on other rectangular areas.

3. When you finish zooming, press ESC, click the Select button on the toolbar, or choose Select > Select from the popup menu. Note that pressing ESC does not work if you are using the Java Edition of the Viewer on an Apple Macintosh computer.

 
Zooming to Selected Map Features

After you select features in a map, you can zoom in to display just enough of the map to show those features.

To zoom to selected map features

1. Select one or more features.
2. Right-click in the map, and then choose Zoom > Selected from the popup menu.

Saving the Current View in a Bookmark

After you zoom and pan to position the map exactly as you want it, you can save the current view of the map as a bookmark. A bookmark saves all of the information about the current view of the map under a name you specify.

The name you type or select for your bookmark cannot contain any commas (,), question marks (?), ampersands (&), or pound symbols (#).
