KmlAltitudeMode Enum

Indicates to ignore an altitude specification (for example, in the tag).

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.

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.
