Displaying and Using Layers


One of the things that makes Google Earth so useful is its capability to overlay other data on top of its maps. This data is added in the form of layers; available layers can be enabled via the Layers pane.

You've already seen several different types of layers in use. When you enabled the 3D buildings and terrain features, you added these layers to the underlying map. Disable the feature, and the layer is taken away.

Tip

In the Layers pane, layers are organized in folders. Double-click a folder to see and activate specific layers within the major layer category.


There are many other kinds of layers you can add to most Google Earth maps. Table 20.4 details some of what's available:

For example, Figure 20.24 shows a view of La Jolla, California with the Roads layer enabled; Figure 20.25 shows the same area with the Lodging layer enabled. At a longer view, Figure 20.26 shows the San Diego area with the Postal Codes layer enabled. You get the point.
