Virtual earth is a Microsoft product that is able to provide aerial
imagery and road maps. The “road” setting adds streets and street names to
your map, The aerial gives you a basic satellite image, and the “hybrid” gives
you a satellite image along with city names and state borders, Enabling you to
be able to view your working area satellite image background. To add this
layer all you need to do is click on the Virtual Earth icon. This icon is located in
the Data Ribbon, and
It is located in the GIS Services Toolbar below the Ribbon.
Once Virtual Earth is added to the map, it will appear in the layers list.
There are three types of maps Virtual Earth can display; Road, Aerial, and
Hybrid. The map above shows the Aerial Map. You can see this because the
word Aerial in the layer list has a check by it. If you would like to switch the
type of map, then click in the box next to the type of map you want displayed.
The map below displays a road map.
The last type of map you can display is the Hybrid map. Click on the box next
to Hybrid to display this type of map. Hybrid will show aerial photos and road
information at the same time.
If you enter the layer properties of Virtual Earth, you can click on the details
button to get some more options.
Clicking on the image type drop down will let you change the map to Aerial,
road, or hybrid. The default level lets you set the resolution level to whatever
you want. The higher it is the better the picture is going to be, but you will get
a longer loading time.
