I solved some well:
function notilt(event) {
var lookAt = ge.getView().copyAsLookAt(ge.ALTITUDE_RELATIVE_TO_GROUND);
lookAt.setTilt(0);
ge.getView().setAbstractView(lookAt);
}
google.earth.addEventListener(ge.getGlobe(), 'mousemove', notilt);
Another thing I have not managed to solve it completely eliminate the relief. In the program if it can be done but the plugin does not know the method.
Does anyone know how to do?
