Detect if Google Earth Plugin is in Street View mode - google-earth

Question

I just want to know if there is any way to determine if the current Google earth plug-in is in street view mode or not.

Answer 1

To test if street view is enabled in the Google Earth plugin:
var navcontrol = ge.getNavigationControl();
var response = navcontrol.getStreetViewEnabled(); // default=false
// response: true -> enabled; false -> disabled
if (!response) {
// to enable street view mode
navcontrol.setStreetViewEnabled(true);
}
If street view is enabled by calling setStreetViewEnabled(true) then user will be able to interactively enter StreetView by manually zooming in (or using pegman).
Note the API docs documents calling ge.getPlugin().streetViewEnabled(true) but this is an error since the getPlugin() method does not exist. The correct method is calling getNavigationControl().
Here's how to test if street view mode is active:
var la = ge.getView().copyAsLookAt(ge.ALTITUDE_RELATIVE_TO_GROUND);
var viewerOptions = la.getViewerOptions();
if (viewerOptions) {
var state = viewerOptions.getOption(ge.OPTION_STREET_VIEW);
if (state == ge.OPTION_STATE_ENABLED) {
// street view mode is active
// do something here
}
}
// if viewerOptions is null then no modes are active
State can be one of three values:
GEPlugin.OPTION_STATE_DEFAULT (0)
GEPlugin.OPTION_STATE_ENABLED (1)
GEPlugin.OPTION_STATE_DISABLED (2)
