Class AltitudeMode

  • public final class AltitudeMode
extends Object
    Specifies how altitude components in the <coordinates> element are interpreted. Possible values are - clampToGround - (default) Indicates to ignore an altitude specification (for example, in the <coordinates> tag). - relativeToGround - Sets the altitude of the element relative to the actual ground elevation of a particular location. For example, if the ground elevation of a location is exactly at sea level and the altitude for a point is set to 9 meters, then the elevation for the icon of a point placemark elevation is 9 meters with this mode. However, if the same coordinate is set over a location where the ground elevation is 10 meters above sea level, then the elevation of the coordinate is 19 meters. A typical use of this mode is for placing telephone poles or a ski lift. - absolute - Sets the altitude of the coordinate relative to sea level, regardless of the actual elevation of the terrain beneath the element. For example, if you set the altitude of a coordinate to 10 meters with an absolute altitude mode, the icon of a point placemark will appear to be at ground level if the terrain beneath is also 10 meters above sea level. If the terrain is 3 meters above sea level, the placemark will appear elevated above the terrain by 7 meters. A typical use of this mode is for aircraft placement.
